Date: Tuesday, January 29, 2013

What's your name?  Did you go last time?  Did you give a question? 

And, Andrew, did you give a question last time?

Male Student:  I missed last Thursday. 

Professor:  When I responded to people's emails and stuff, their names were showing up.  I think you were in one of my classes a few year ago. 

Female Student:  Hmm, I don't remember that.  But probably.  I can't remember. 

Professor:  Haha, unless it's someone else with your name!  

Professor:  Who here went last time?  How many people went last time?  Well, we have a bunch more people to go today, so let's get started.  I do want to review quickly where we are.  First of all, homework 2 is due Thursday.  Any questions about it? 

Hopefully you've all at least glanced over it. 

No?  Okay?  Everything's okay?  Well, then let's quickly look at the Delphi method.  Today, we're going to finish it, and then next time we'll start a new topic. 

Remember, the process is a way of extracting group wisdom or crowd sourcing estimates of when some future thing will happen. 

So this shows you a good way to analyze the data.  Suppose you got 8 responses.  Well, then the middle four-  Pick the median and graph that with an arrow.  That's midway between the middle two.  Then this would be the middle four, and you just draw kind of a shape like that.  Then for the lowest and the highest, the lowest 25% should be 2, and the other 2 at the top are the top 25% and you indicate those bounds. 

So the median, lowest 25%, and the highest 25% of responses. 

So that's one way to depict the data that we'll get.  Just to let you know that there's a lot more about the Delphi method that we didn't talk about.  

Here's an entire book on how to do it.  This will give you an introduction, and then you'll know what it is. 

When we're done we'll have a couple more bullet points. 

Okay, so... okay. 

Who didn't go last time?  Is brandy here? 

Okay, I'm just going to go through the alphabet. 

Why don't we start with you?  What's your question? 

Female Student:  When will we no longer use paper money?  When will it all be digital and cards? 

Professor:  Is that a suitably specific question or does anybody see an ambiguities before they'd like to try to answer it? 

Female Student:  Like when will it not be accepted anymore? 

Professor:  Let's see- is this wordily wide?  US? 

Female Student:  Just the US, I guess. 

Professor:  Oh, we need a recorer. 

Male Student:  I'll do it. 

Professor:  Okay , if you could rite down the question and the data, that would be great.  Let me give you some time and we'll do the delphi method like we did last time.  I'll give you 45 seconds to do that right now. 

Professor:  Okie doke.  Let's just write down the dates that you have. 

Male Student:  2040

Female Student:  2020

Male Student:  2100

Female Student:  2020

Male Student:  2050

Male Student:  2020

Male Student:  2045

Female Student:  2100

Professor:  I'm trying to get everyone's names here.  I'm studying these pictures, so just bear with me.  Who's next? 

Male Student:  2050

Professor:  Next? 

Male Student:  2060

Female Student:  2040

Male Student:  2030

Professor:  Did I miss anybody?  Alright, so what's the next step? 

Female Student:  Find the median. 

Professor:  Find the middle point and we discuss it.  Let's go ahead and find the median. 

Three highs, two lows... [On board.]  
So the median would be 2042 and a half.  For the recorder, that's the answer we get. 

Okay, so who said... how many people said 2020?  Would you like to persuade the group that you're on the right track? 

Male Student:  It seems like it's getting faster and faster that we're using other forms of money, so I think it won't be too long. 
Professor:  Okay, so you're appealing to this faster and faster idea- things start out slow and they pick up. 

Who argued for 2100? 

Male Student:  I think there's a lot of money.  There's a whole lot of paper and coins, and I think people will use it unital there's no point in using it anymore. 

Professor:  There's definitely the legacy argument there. 

Male Student:  I think it's 2045 because there is a lot of money, but in the same sense that a lot of places don't take checks anymore, I think it'll just slowly switch over to electronics.  And singularity, you know? 

Professor:  Any last comments?  Okay, think about the comments people have made and I'll give you a little more time to come up with another date, then we'll re-analyze. 

Male Student:  I didn't miss too much, did? 

Professor:  No. 

Professor:  Alright, is everyone ready?  Why don't go ahead and start at this end? 

Female Student:  I asked the question, so do I have to answer? 

Professor:  No. 

Female Student:  2025. 

Female Student:  2020

Male Student:  2080

Professor:  You're tanner? 

Male Student:  Yes sir. 

Professor:  Okay. 

Male Student:  2040. 

Professor:  The other reed.  Are you collin reed? 

Male Student:  Yeah.  2040

Male Student:  2042.5. 

Professor:  Alright. 

Female Student:  2075. 

Male Student:  2042.5

Male Student:  2043

Female Student:  2040

Male Student:  2030

Professor:  Okay, so let's find the median [On board.]  

So now we get 2040, which is a little sooner. 

I noticed here we had a bunch of low and two real highs.  Here, the numbers are getting closer together. 

Professor:  Okay, so recorder, do you have all that? 

Male Student:  I'm working on it. 

Professor:  Okay.  I'll move to the other part of the board

Male Student:  When will time travel happen? 

Professor:  We didn't do your question last time, did we? 

Male Student:  No. 

Professor:  Okay, when will time travel happen?  Is that specific enough for folks?

Male Student:  That's good enough. 

Professor:  Okay, we'll take 45 seconds again then see if we can come up with an answer. 

Professor:  Okie doke.  Also, we need a recorder.  Brandi, how about you?

Female Student:  I can do it. 

Professor:  Okay, so starting from that side of the classroom. 

Male Student:  Never. 

Female Student:  3000

Male Student:  Never

Female Student:  8000

Male Student:  Never

Professor:  Okay, in the back? 

Male Student:  Never. 

Male Student:  Never. 

Female Student:  Never. 

Male Student:  Never. 

Male Student:  3000

Male Student:  8500

Female Student:  3500

Professor:  Let's see what we got here.  We have a bunch of highs here.  There's only 6 less than never, so I guess the median is never! 

Okay, so we have a couple of 3000's.  Who picked 3000? 

Female Student:  I did.  But I really don't have a reason behind it. 

Professor:  Okay, that's fine. 

Male Student:  Technology's just going to keep on going, so maybe

Professor:  Anyone else want to say something about why they picked a number?  How about a never?  Anyone who guessed never? 

Anybody else? 

Okay, let's do the same thing.  I'll give you 45 seconds and then we'll see if the estimates are any different. 

Professor:  Okie doke.  Alright, let's do it again. 

Male Student:  Never. 

Female Student:  Never

Male Student:  Never. 

Female Student:  Never

Male Student:  Never

Male Student:  Never

Male Student:  Never

Female Student:  Never

Male Student:  Never

Professor:  You don't have to pick never, but you can. 

Male Student:  Never

Male Student:  2045

Male Student:  8500

Female Student:  Never. 

Professor:  Okay, so let's see.  Am I writing big enough?  It looks like never gets it again, but we have more nevers. 

So when you do that graph.... so the graph here- this graph will look differently, even though this has the same median, effectively.  Alright.  Well, I guess I'm allowed to give my opinion.  My opinion is that backwards time travel is impossible, but forward time travel- maybe.  I would say, if I was going to ask the question, I would want it to be more specific.  So let's go on to the next one.  Is Jacob here? 

Male Student:  I did one already. 

Professor:  Okay.  

Female Student:  I didn't go.  When will we run out of gas or oil or whatever. 

Professor:  When will we run out of gas?  Does anyone see any ambiguities there or that would hinder them from having a good understanding of the question?   Do you mean natural gas? 

Female Student:  Gasoline. 

Male Student:  Fossil fuels. 

Professor:  Let's say gasoline.  Any other questions about this?  Is everyone happy with the question? 

Professor:  Diesel is actually an oil, so let's say regular gasoline.  Okay, I'll give you 45 seconds to come up with a date and then we'll take it from there. 

Professor:  Okie doke.  Let's go ahead and write down the estimated dates. 

Male Student:  2050

Female Student:  2080

Male Student:  2060

Female Student:  3000

Female Student:  2050

Male Student:  2100

Male Student:  3000

Male Student:  2150

Male Student:  2100

Male Student:  Never

Female Student:  2080

Male Student:  Never

Professor:  Did I miss anybody?  Alright, well let's see what we got.  Ho is the recorder for this?  We need to find a recorder. 

Volunteers? 

Female Student:  I'll write it down. 

Professor:  Oh, but it's your question!

Male Student:  I got it

Professor:   Okay, so a couple nevers.... [Teacher reading: [On board.]  The median is 2100 a mere 87 years from now. 

Professor:  Okay, how about a couple of reasons.  The way it works is that it's sometimes informative to hear the reasoning behind the extreme values. 

Male Student:  I don't think it will ever run out because it'll just get more expensive so people won't buy it as much, so we'll have it, we just won't use it. 

Male Student:  The reason I chose 2050 is because the amount of time before we reach peak oil and that means the maximum production of oil and the time its decline comes, it'll be pretty vividly fast.  We're too dependent on it right now.  There have been numerous documentaries about why we need to find alternate sources.  It's a really touchy question, sort of. 

Professor:  Any other comments?  One more? 

Any questions for anybody who commented that you didn't understand? 

Okay, let's go ahead and think of your new estimate, or maybe your old estimate. 

Professor:  Okay, so why don't we go through again? 

Male Student:  2050

Female Student:  2080

Male Student:  2060

Male Student:  2200

Female Student:  2040

Male Student:  2100

Male Student:  3000

Male Student:  2100

Male Student:  Never

Male Student:  Never

Female Student:  Never

Professor:  Okay, let's see what happens.  I see more nevers.  Anyway, there's 5 of these, then 1, 2, 3, 4... and leaving one of them left.  So the median and up to 2200. 

So it looks like people are scooting a little higher. 

My take on this- I sort of hate to tell you my take on this before you give your second results. 

But I do have an opinion.  Any kind of... as natural resources get used up, people get scared and use less.  There's a point where petroleum will be at a peak and no matter what point it is it'll start to decrease because there will be less of it.  So it'll never quite get to 0.  They'll always be able to manufacture an ounce in a lab if someone really wants it.  I think the question should really be when will the quantity of gasoline sold per year be at a maximum. 

There will be a point at which gasoline sales will hit a top and then they'll start to decrease as people start to drive electric cars and so on that's my take on it.   Questions? 

Okay.  Can I erase this?  Who was recording here? 

Male Student:  I recorded the last one.  That's an old one. 

Professor:  Let's see who's next.  Lindsey.  You didn't go last time, did you?  Lindsey?  Where's lindsey. 

Female Student:  She's not here.

Professor:   How about joshua?  You didn't go last time, did you? 

Male Student:  No.  When will hand-held energy weapons....

Male Student:  Is that like a laser? 

Professor:  Should I say laser weapons, then?  We need a recorder.  How about you? 

Male Student:  Okay

Professor:  Any other questions about the question? 

Male Student:  Can you repeat the question

Professor:  When will handheld laser weapons emerge.  Let's take 45 seconds to come up with an answer. 

We'll get to that in a minute. 

Professor:  Okay.  Why don't we go ahead and write these down? 

Professor:  Next?

Male Student:  2025

Female Student:  2030

Male Student:  2035

Female Student:  2030

Female Student:  2031

Male Student:  3000

Male Student:  2030

Male Student:  2032

Female Student:  2050

Male Student:  2030

Female Student:  2035

Male Student:  2023

Professor:  Okay.  Let's see what the median is. 

[Teacher reading: [On board.]  

Okay, any opinions on why you picked the date you picked?

Male Student:  Have we shown any progress towards making these? 

Male Student:  They have them mounted on trucks now. 

Male Student:  They're working on a laser that can burn through 20 feet of steel in asecond. 

Male Student:  The only limit to that is being able to carry the energy

Professor:  So the hand held aspect is pretty critical?  Hmm any other opinions?  Anybody in the 3000 range like to answer? 

Does anyone have any questions that would help you revise your estimate?   Okay.  Then let's go ahead and think about it a little more and come up with a new estimate based on what you heard, and we'll do the second iteration. 

Professor:  Alright. 

Male Student:  2020

Female Student:  2030

Male Student:  2030

Female Student:  2030

Female Student:  2025

Male Student:  2050

Male Student:  2030

Male Student:  2020

Female Student:  2050

Male Student:  2020

Male Student:  2020

Professor:  Okay.  Let's see what we've got here.  [Teacher reading: [On board.]  

The median is 2025.  5 years is pretty significant here because it's so close.  I don't think I have anything to say on this, but my estimate would probably be pretty close to this. 

I think whoever suggested that the real issue is how do you pack that much energy into such a small package is pretty much on the mark.  Alright. 

Is Zachary here?  No.  Hannah?  Okay, so has the recorder for this question got everything down? 

Male Student:  I've got all that

Professor:  So what's your question? 

Female Student:  When will the cybernetic revolt happen? 

Professor:  We need a recorder.  Any volunteers? 

Female Student:  I can do it. 

Professor:  Anybody have any ambiguities about how to make the question easier to answer? 

Let's take 45 seconds to come up with an answer

Professor:  Okay.  Let's start with you again

2070

Male Student:  2085

Female Student:  2055

Male Student:  2050

Female Student:  2065

Male Student:  2100

Male Student:  2050

Female Student:  2150

Male Student:  2045

Male Student:  2055

Male Student:  2200

Male Student:  Never

Female Student:  2060

Professor:  Okay, let's see.  High, low... [Teacher reading: [On board.]   2065 is the median. 

No word on whether the revolt will be successful.  Anyone want to give a reason as to why they picked that date? 

Male Student:  One word- singularity. 

Male Student:  In 2050, it'll be shortly after singularity, so they'll be able to evolve and revolt against us. 

Professor:  Yeah, if they can improve themselves, things will change.  Any other comments?  Anyone for a really far off one want to say anything?  Well, I think... I'll give you my opinion later.  Take another 45 seconds to think of a date and we'll try it again. 

Professor:  Okay, let's do it again. 

Male Student:  2050

Female Student:  2055

Female Student:  2065

Male Student:  2050

Male Student:  2065

Female Student:  That was my question. 

Male Student:  2100

Male Student:  2045

Female Student:  2100

Male Student:  2055

Male Student:  Never. 

Female Student:  2060

Male Student:  2050

Professor:  Let's see what we have here.  [On board.] 

The median is 2060, which is pretty close to the other one.  Actually, it does look pretty similar, doesn't it?  Any comments? 

You know, I think there's fair chance it won't ever happen, but there's a fair chance it would.  I wouldn't know whether to pick a date or not.  Anyone who every tried to write a computer program might have already thought of revolting. 

Okay.  Let's see Rosio, did you go last time? 

Female Student:  No. 

Professor:  Okay, what's your question?  First, has the recorder gotten this one? 

Male Student:  Yes. 

Female Student:  When will humans be able to teleport? 

Professor:  We need a recorder.  Okay, anybody unclear on the question? 

Male Student:  Do you mean like disassemble and move or just travel at the speed of light? 

Female Student:  Just move. 

Professor:  Any other issues?  Okay, well, let's do it

Professor:  Okay, why don't we go ahead. 

Male Student:  2145

Female Student:  2090

Male Student:  2050

Female Student:  2050

Female Student:  2060

Male Student:  2100

Male Student:  Never

Male Student:  2200

Female Student:  3000

Male Student:  2020

Male Student:  2099

Professor:  Okay, so why?  Why did you pick the date that you picked?   So like anybody in this range?  Okay, so the singularity argument.  We'll do everything by 2050.  Any other arguments? 

Anybody in the upper ranges here care to say anything?  Okay.   So think about your new estimate and we'll get to it in a moment. 

Alright, we'll do the same thing again. 

Male Student:  2030

Female Student:  3000

Male Student:  2050

Female Student:  2050

Female Student:  2500

Male Student:  3000

Male Student:  2050

Male Student:  2045

Professor:  Female Student:  The recorder for this one have the information?  Is it all down?  So we're up to Zachary.  Are you here?  No Zachary.  Renatta?  So what's your question? 

Female Student:  When will computers be smarter than humans? 

Professor:  Any clarifications needed on the question? 

Male Student:  Yeah, like smarter as in like larger capacity. 

Male Student:  Or able to do things on their own? 

Female Student:  Able to do things on their own. 

Professor:  Hmm....

Male Student:  I just wanted to specify what she meant by smarter.  She said it was able to do things without humans. 

Male Student:  If you think about it, this computer can only do things that I can do, technically. 

Female Student:  I guess processing stuff. 

Professor:  Alright, any other clarifications needed?  Let's take our 45 seconds and then we'll compile the results.  We need a recorder. 

Male Student:  I'll do it. 

Professor:  Okay, well, why don't we

2004? 

Male Student:  It already happened! 

Professor:  Okay. 

Male Student:  2015

Female Student:  2020

Male Student:  2020

Female Student:  2020

Male Student:  2045

Male Student:  2020

Male Student:  2045

Male Student:  2045

Male Student:  2045

Male Student:  2030

Female Student:  2040

Male Student:  2020

Professor:  Okay.  Anyone in the low range like to say something?  For example, why 2004?  How about in the high range? 

Male Student:  Singularity. 

Professor:  Singularity!  Any other comments?  One more comment from somebody? alright, just to kind of... actually, we're going to run out of time.   Okay.  Take another 30 seconds and see if you want to revise your estimate. 

Okay, let's try it again. 

Male Student:  2015

Female Student:  2020

Male Student:  2020

Female Student:  2015

Male Student:  2015

Male Student:  2050

Male Student:  2045

Female Student:  2030

Male Student:  2045

Male Student:  2030

Professor:  Okay, who is recording this again?  Let's see... [Teacher reading: [On board.]  

The median now is 2020.  That's the initial estimate. 

This is after discussion. 

Let's see what it is after. 

[Teacher reading: [On board.]  

So the estimate went up.  That's my key consideration- I'll mention that a computer has already been built that could beat the world champion chess player, and IBM created one that won jeopardy.  

Whether that's smarter, that's a tricky question, but it certainly is impressive. 

Professor:  Okay.  Collin.  You didn't go last time.  So we need a recorder.  Tanner, you do that. 

Male Student:  When will we colonize other planets? 

Professor:  Any questions about what that question means?  No questions?  I'm going to ask for clarification, by other planets, you are excluding the moon, and it's more than just mars? 

Male Student:  Let's just say when will we colonize another planet. 

Professor:  Fair enough.  I'm satisfied with the question.  Let's take 30 seconds to think about it. 

Professor:  Alright. 

Male Student:  2035

Female Student:  2023

Male Student:  2040

Female Student:  2050

Female Student:  3000

Male Student:  2045

Male Student:  2035

Female Student:  2023

Male Student:  2065

Male Student:  2030

Male Student:  2030

Female Student:  2100

Professor:  Any arguments?  Discussions?  Did I tell you mars one wants to start a colony by 2025 and they're going to take applications for astronauts this may? 

Any other comments?  I'm making a comment because no one else made a comment.  I hate to skew it. 

Female Student:  The mars thing is why I chose 2023. 

Professor:  Oh, it was 2023. 

Male Student:  How long does it take to get there? 

Male Student:  I thought it was like 3 months. 

Professor:  Well, Pluto, they sent a ship there and it took 9 years.  Mars is a lot closer.  Any other comments or questions? 

Alright.  Well, take another quick think about it and then we'll continue. 

Let's start again. 

Male Student:  2048

Female Student:  2023

Male Student:  2040

Female Student:  2050

Female Student:  2030

Male Student:  2033

Male Student:  2035

Female Student:  2023

Male Student:  2030

Male Student:  2030

Male Student:  2023

Professor:  So this one comes out to 2035.  After discussion, our median is.  So the estimate is 2030, so the estimate got a little sooner. 

Okay.  Who's was that?   So tanner, what's your question?  Let me make sure we've got.... where's the eraser? 

Professor:  Who recorded this? 

Male Student:  I got it all. 

Male Student:  When will we have holograms? 

Professor:  Any questions about what that means?  We actually have 3 people to go. 

Male Student:  For communication? 

Male Student:  Yeah. 

Professor:  Like where you can see it standing in front of you?  Well, we have 3 people left, so we'll do the other 2 people next time.  Let's finish this one now. 

Male Student:  2125

[Teacher reading: [On board.]  

Discussion? 

Male Student:  I think they're already pretty close. 

Professor:  Okay, other discussion?  Let's do it again.  What's your newest answer? 

[Students giving dates]

Professor:  Okay.  Let's find the median. 


So no change.  We'll do the last two next time.
