First, I think there is a world of difference between passionate
researchers at the beginning of the field, in 1956, and passionate
researchers in 2008 who have a half-century of other people's mistakes
to learn from. The secret of success is to try and fail, then to try
again with a fresh outlook. That exactly fits the new AGI crowd.
Are you suggesting that the early researchers (not just the 50s, but
also the 60s, 70s and 80s) weren't learning from each other's mistakes?
If so, I think you need to address why this generation is able to learn
from past mistakes, when prior generations couldn't learn from each other?
Second, when you say that "a better argument would be to point to a
fundamental technological or methodological change that makes AGI
finally credible" I must say that I could not agree more. That is
*exactly* what I have tried to do in my project, because I have
pointed out a problem with the way that old-style AI has been carried
out, and that problem is capable of neatly explaining why the early
optimism produced nothing. I have also suggested a solution to that
problem, pointed out that the solution has never been tried before (so
it has the virtue of not being a failure yet!), and also pointed out
that the proposed solution resembles some previous approaches that did
have sporadic, spectacular success (the early work in connectionism).
However, in my Open Letter post, I did not want to emphasize my own
work (I will do that elsewhere on the website), but instead point out
some general facts about all AGI projects. Perhaps I should have also
said "And I have an approach that is dramatically new....", but I felt
that that that would have weakened the points that I was tryingt to make.
I don't think you need to say that.
Hypothetically, if you were to believe that your own project is the only
one with a chance of success, then encouraging investment in AGI would,
given such beliefs, surely only discredit the field when money is later
found to have been wasted with no results.
In contrast, I think that you believe there are many people with good
ideas and that there is "change in the air": researchers really are
starting to tackle AGI in interesting and promising new ways; and that
you are just one of many groups with fresh and plausible ideas for
building an AGI.
So, why not try to pinpoint and express such changes (and their cause)
in your letter?
Finally, I do have to point out that you made no comment on the second
part of the post, where I explained that *any* investor who put money
into any project in the AGI arena would be injecting a shot of
adrenalin into the whole field, causing it to attract attention and so
stimulate further investment. That is a very important point: in any
other field of investment the last thing you want to do is to provoke
other investors into funding rivals to your own investment, but in AGI
nothing could be better. If that shot of adrenalin into the AGI field
caused one of the projects to succeed, the result would be a massive
technology surge that would benefit everyone, not just the individual
investor. There is no other investment opportunity where so much
"trickle-down" could be generated by the success of one company.
That argument lessens the risk of the investor's money being wasted.
I didn't comment on the second part of the email because I don't want to
get involved in arguments about singularity.
Since you bring up the second part, I will add some comments about your
claims that an investor wouldn't/shouldn't care if they back a "bunch of
idiots... [that] burn all the cash and produce nothing", because it will
create buzz and lead to many projects. You say that if "just one of
them" succeeds then all AGI investors will personally benefit (even if
they weren't investing in the particular company that succeeds).
Your assumption here is that the chance of "just one of them" succeeding
is quite good. This brings us right back to my comments on the first
half of your letter: you haven't really offered an investor a convincing
argument for why the chances are good that *somebody* will succeed this
time, when talented passsionate people have been trying for years and
failing.
You're also bringing up themes related to singularity, and I don't think
this is necessary. I (and many others here have expressed a similar
opinion) think that AGI can have many benefits and applications even if
it takes a very long time to get to super-intelligence. If you can
justify investment in AGI even with a pessimistic outlook (but the
possibility of radical change), then you would have a much better case.
And finally, I really don't think it is good advice to say "oh, just
throw money about, and create buzz, without a care for who receives it".
If AGI researchers were to receive huge amounts of money (and buzz) but
end up failing again, the reputation of the field and the chance of
finding *any* investment could be severely hurt. Historians looking over
the years following a failed AGI buzz (bubble?) may call it the AGI Winter.
It sounds very suspect when you tell investors not to be overly
discriminating with their money. It would be much better to encourage
investors to follow the field and understand it - invest their time,
rather than their money - so that when they find something they believe
in (even if it takes 10 years to find it), they will be the ones on the
cutting edge. If they find something today, then that is fantastic.
I hope you do revise and improve your open letter. If we want AGI to be
taken seriously, then it is our responsibility to engage the public with
as much professionalism and polish as possible.
