Re: [agi] Re: AI isn't cheap

2008-09-11 Thread Matt Mahoney
I suppose in order to justify my cost estimate I need to define more precisely 
what I mean by AGI. I mean the cost of building an automated economy in which 
people don't have to work. This is not the same as automating what people 
currently do. Fifty years ago we might have imagined a future with robot gas 
station attendants and robot sales clerks. Nobody imagined self serve gas or 
shopping on the internet.

But the exact form of the technology does not matter. People will invest money 
if there is an expected payoff higher than market driven interest rates. These 
numbers are known. AGI is worth $10^15 no matter how you build it.

An alternative goal of AGI is uploading, which I believe will cost considerably 
less. How much would you pay to have a machine that duplicates your memories, 
goals, and behavior well enough to convince everyone else that it is you, and 
have that machine turned on after you die? Whether such a machine is "you" 
(does your consciousness transfer?) is an irrelevant philosophical issue. It is 
not important. What is important is the percentage of people who believe it is 
true and are therefore willing to pay to upload. However, once we develop the 
technology to scan brains and simulate them, there should be no need to develop 
custom software or training for each individual as there is for building an 
economy. The cost will be determined by Moore's Law.

(This does not solve the economic issues. You still have to pay uploads to 
work, or to write the software to automate the economy).

If it is possible. However, there is currently no model for recursive self 
improvement. The major cost of "write a program to solve X" is the cost of 
describing X. When you give humans a programming task, they already know most 
of X without you specifying the details. To tell a machine, you either have to 
specify X in such detail that it is equivalent to writing the program, or you 
have to have a machine that knows everything that humans know, which is AGI.

Good question. Everything you have learned through language is already known to 
somebody else. However, the fact that you learned X from Y is known only to you 
and possibly Y. Some fraction of nonverbally acquired knowledge is unique to 
you also.

What fraction is relevant? Perhaps very little if AGI means new ways of solving 
problems rather than duplicating the work we now do. For other tasks such as 
entertainment, advertising, or surveillance, everything you know is relevant.

WOW, my very favorite subject, since it so greatly overlaps with so many
religions. My claim is that most people are NOT sufficiently unique to claim
that they have any soul at all, so there is nothing for them to
"save", especially through prayer that probably works to further standardize
their brains. Public education also works great for soul-elimination.

You want to replicate the work currently done by 10^10 human brains.


Hmm.  Actually probably only some 10^6 of them at most are doing  
anything much worth replicating.  :-)


A brain has 10^15 synapses. A neuron axon has an information rate of  
10 bits per second. As I said, you can argue about these numbers but  
it doesn't matter much. An order of magnitude error only changes the  
time to AGI by a few years at the current rate of Moore's Law.


Software is not subject to Moore's Law so its cost will eventually  
dominate.


So creating software creating software may be a high payoff subtask.

A human brain has about 10^9 bits of knowledge, of which probably  
10^7 to 10^8 bits are unique to each individual.


How much of this uniqueness is little more than variations on a much  
smaller number of themes and/or irrelevant to the task?


That makes 10^17 to 10^18 bits that have to be extracted from human  
brains and communicated to the AGI.


What for?  That seems like a very slow path that would pollute your  
AGI with countless errors and repetition.


This could be done in code or formal language, although most of it  
will probably be done in natural language once this capability is  
developed.


Natural languages are ridiculously slow and ambiguous.  There is no  
way the 10^7 guesstimated unique bits per individual will ever get  
encoded in natural language anyway (or much of anything else other  
than its encoding in those brains).


Since we don't know which parts of our knowledge is shared, the most  
practical approach is to dump all of it and let the AGI remove the  
redundancies.


Actually, of the knowledge the AGI needs we have pretty good ideas of  
how much is shared.


This will require a substantial fraction of each person's life time,  
so it has to be done in non obtrusive ways, such as recording all of  
your email and conversations (which, of course, all the major free  
services already do).


What exactly is your goal?  Are you attempting to simulate all of  
humankind?   What for when the real thing is up and running?If you  
want uploads there are more direct possible paths after the AGI has  
perfected some crucial technologies.






The cost estimate of $10^15 comes by estimating the world GDP ($66  
trillion per year in 2006, increasing 5% annually) from now until we  
have the hardware to support AGI. We have the option to have AGI  
sooner by paying more. Simple economics suggests we will pay up to  
what it is worth.


Why believe that the real productive intellectual output of the entire  
human world is anywhere close to or represented by the world GDP?   It  
is not likely that we need to download the full contents of all human  
brains including the huge part that is mere variation on human primate  
programming to effectively meet and exceed this productive  
intellectual output.  I find this method of estimating costs utterly  
unconvincing.

(Top posting because Yahoo won't quote HTML email)

Steve,
Some of Google's tech talks on AI are here:
http://www.google.com/search?hl=en&q=google+video+techtalks+ai&btnG=Search

Google has an interest in AI because search is an AI problem, especially if you 
are searching for images or video. Also, their advertising model could use some 
help. I often go to data compression sites where Google is advertising 
compression socks, compression springs, air compressors, etc. I'm sure you've 
seen the problem.

Since you have experience writing sophisticated software on very limited 
hardware, perhaps you can enlighten us on how to exponentially reduce the cost 
of software instead of just talking about it. Maybe you can write AGI, or the 
next version of Windows, in one day. You might encounter a few obstacles, e.g.

1. Software testing is not computable (the halting problem reduces to it).

2. The cost of software is O(n log n). This is because you need O(log n) levels 
of abstraction to keep the interconnectivity of the software below the 
threshold of stability to chaos, above which it is not maintainable (where each 
software change introduces more bugs than it fixes). Abstraction levels are 
things like symbolic names, functions, classes, namespaces, libraries, and 
client-server protocols.

3. Increasing the computational power of a computer by n only increases its 
usefulness by log n. Useful algorithms tend to have a power law distribution 
over computational requirements.

No it would not. Assuming we had the technology to copy brains (which we don't 
and you don't), then you have created a machine with human motives. You would 
still have to pay it to work. Do you really think you understand the brain well 
enough to reprogram it to want to work?

>Further, I see the interest in AGIs on this forum as a sort of

No, it is about the money. The AGIs that actually get built will be the ones 
that can make money for their owners. If an AGI can do anything that a human 
can do, then that would include work. Currently that's worth $66 trillion per 
year.

Here I could write a book and more. It could and should obey Moore's law,
but history and common practice has gone in other directions. Starting with
the Bell Labs Interpretive System on the IBM-650 and probably peaking at
Remote Time Sharing in 1970, methods of bootstrapping to establish a
succession of higher capabilities to grow exponentially have been known.
Imagine a time sharing system with a FORTRAN/ALGOL/BASIC all rolled into one
memory-resident compiler, significance arithmetic, etc., servicing many of
the high schools in Seattle (including Lakeside where Bill Gates and Paul
Allen learned on it), all on the equivalent of a Commodore 64. Some of the
customers complained about only having 8kB of Huffman-coded
macro-instructions to hold their programs, until a chess playing program
that ran in that 8K that never lost a game appeared in the library. Then
came the microprocessors and all this has been forgotten. Microsoft sought
to "do less with less" without ever realizing that the really BIG machine
they learned on (and which they still have yet to equal) was only the
equivalent of a Commodore 64. I wrote that compiler and chess game.

No, the primary limitation is cultural. I have discussed here how to make
processors that run 10,000 times faster, and how to build a scanning UV
fluorescent microscope that diagrams brains. The SAME thing blocks both -
culture. Intel is up against EXACTLY the same mind block that IBM was up
against when for decades they couldn't move beyond Project Stretch, and
there simply isn't any area of study into which a Scanning UV fluorescence
microscope now cleanly falls, of course because without the microscope, such
an area of study could not develop. Things are now quite stuck until either
the culture changes (don't hold your breath), or the present generations of
"experts" (including us) dies off.

At present, I don't expect to see any AGIs in our lifetime, though I do
believe that with support, one could be developed in 10-20 years. Not until
someone gives the relevant sciences a new name, stops respecting present
corporate and university structure (e.g. that PhDs have any but negative
value), and injects ~$10^9 to start it can this happen. Of course, this
requires independent rather than corporate or university money - some
rich guy who sees the light. Until I meet this guy, I'm sticking to
tractable projects like Dr. Eliza.

I looked at your file. Would I be correct that if I described a random
health
problem to Dr. Eliza that it would suggest that my problem is due to one of:

- Low body temperature
- Fluorescent lights
- Consuming fructose in the winter
- Mercury poisoning from amalgam fillings and vaccines
- Aluminum cookware
- Hydrogenated vegetable oil
- Working a night shift
- Aspirin (causes macular degeneration)
- Or failure to accept divine intervention?

= First, my complements on your careful reading of the knowledge base.

= Yes, there is a pretty good chance that you would be asked about some of
these things, as various of these things seem to underlie most chronic
illnesses.

Is that it, or is there a complete medical database somewhere,

= WYSIWYG, though this is only maybe 1% of a fully populated
health database. This stuff is just there for demo. For a 1% demo, it works
amazingly well. Further, I presume that people would embed generous
hyperlinks into the explanations, so that Pub Med and other medical
databases would be just a mouse click away.

or the capability of acquiring this knowledge?

= Only machine knowledge that has been carefully crafted by humans. As I
have explained in a number of postings, certain key things, like how people
commonly express symptoms and the carefully crafted questions needed to
drill down, are NOT on any web site or medical text, so the services of an
experienced expert is absolutely required. Plans of others to "mine the
Internet" (or Wikipedia) are absolutely doomed to failure because this
information is so completely lacking. No AGI would be able to compose this
knowledge unless they had the real-world experience with real-world people
to know how they express things. In short, many AI and AGI plans are quite
obviously hopeless because they lack access to this information.

Do you have a medical background,

= Yes.

or have you consulted with doctors in building the database?

= Yes.

BTW, regarding processes that use 100% of CPU in Windows. Did you try
Ctrl-Alt-Del to bring up the task manager, then right click on the process
and
change its priority?

= Not that specifically, though I did try the Windows API to do the same,
and got back an error code that indicated that the most problematical task
(NaturallySpeaking) had set a bit to keep other tasks from adjusting its
priority. I presume that the Task Manager would have simply called the same
API but probably failed to provide the return code. I expect to abandon
speech I/O in the future even though it works pretty well, because no one
seems to want to bet their success in overcoming their problems on the
random screwups of a speech recognition program. Without speech I/O, there
is no speed "problem". This is apparently one of those "great ideas" that
just ca
