All the major, credible AGI projects take care to examine the field
of AI, looking for incremental successes to reuse and common pitfalls
to avoid. I still regularly see people starting personal projects and
declaring that 'since all past work failed, it must be irrelevant, so
I don't need to pay much/any attention to it'.

Most relevant recent theoretical progress has been in decision
theory and cognitive science, not in AI as such; AGI projects don't
often reuse technology from earlier, failed AGI projects (or from
other people's AGI projects in general).

Untrue; there are plenty of projects that don't acknowledge the
interdisciplinary requirement (SOAR, Cyc) or which don't require
any radical new theory (CCortex; granted 'advanced' is only
verifiable in retrospect). Brilliance of researchers is something
that people just have to make personal best guesses on.

Yes.

It does apply to the SIAI. Our only defence is that we acknowledge
the depth of the self-delusion problem (and take what steps we can
to detect it). In fact this is another reason I want to do (limited)
prototyping now; if we have serious blind spots, I want to know about
them ASAP. This is also a major reason for Eliezer's push for formally
provable algorithms and techniques for FAI; while deluding yourself
into thinking you have an AGI design when you don't is merely a waste
of time and resources, deluding yourself into thinking you have an
FAI design when you really only have a seed AI design is fatal.

I agree. There are many designs that are theoretically capable of
supporting general cognition; Novamente for example, or even in
principle a Perspex machine (it is Turing complete). However these
designs don't actually specify the required cognitive complexity,
only inductive mechanisms intended to generate it, and I have yet
to see a design where it is demonstrated that these inductive
mechanisms will actually be capable of creating the relevant
'emergent' complexity (given a tractable amount of computation).

Absolutely. If you can't show that a design will work in principle,
it definitely won't work in practice. There are some problem
domains for which this doesn't hold; if the range of possible
solutions is small enough trial and error will eventually come up
with the right answer.

True, but if the demo confirms a good fraction of the predictions
made by a theory of general cognition, the probability of the
other predictions being accurate goes up considerably.

Ideally you want to excite people enough to get them interested
without being so impressive that everyone starts trying to clone
your effort.

By 'what we're going to do' I mean 'the Friendliness architecture
that we're going to implement via the AGI'. I'm not talking about
my speculative seed AI architecture, which right now has only my
opinions in favour of it. I'm reffering to Eliezer's Friendliness
architecture, the implementation of Collective Volition. It's
not complete, but it is definitely the most advanced Friendliness
theory developed to date. No other AGI projects have cracked or
even seriously tackled the Friendliness problem yet (unless there
is something you're not telling us in that regard).

I'm not qualified to research Friendliness theory; I'm relying
on Eliezer's powers of omniscience in that regard ;)

Say what? The vast majority of organisations are companies dedicated
to their stockholders or private clubs dedicated to the interests of
their members. Most AGI projects are in the former category. As for
Collective Volition, if anyone other than the SIAI is planning to
implement it, I haven't heard about it.

James, whoever develops a seed AI first (and manages to meet the
strict requirements for getting it to do something predictable) will
have an awesome moral responsibility. I know you don't think hard
takeoff is likely, but even with soft takeoff the people programming
the initial AGI(s) will have an utterly unprecedented amount of power
over all of humanity. If there is a way to avoid this massive risk,
I'd be all for it, but I'm not aware of one. As such anyone who is
developing AGI is effectively claiming that they have the right to
take the future of the human race into their own hands, and anyone
who wants to support an AGI project is forced to decide who is most
likely to be trustworthy. I can't see what else we can possibly do
than state our intent clearly and try to be as transparent and
honest as possible.
