Granted, once they're replicating it will be pretty much impossible to stop
them, intelligent or not. Hence my concern.

Not really, my intuition is to sandbox AIs tightly (especially the smart
ones) until we can be sure they aren't going to go do something stupid
(which is highly likely to begin with) in the real world.
I get very nervous when I hear about AI improving itself. It's like doing
brain surgery on yourself. What if you damage an area that affects your
judgement & you start making random modifications? Instabilities are most
likely to result, to say the least.
You could have some nice trustworthy AI's perception suddenly change because
of some unforeseen modification, and because the AI is modifying itself,
it's new perception will further affect it's modifications.
I prefer an architecture without that kind of internal feedback.
I'm well aware that thinking is itself a form of self-modification, but on a
different level. We can't modify major parts of our neural architecture by
Actually this stability problem is a large part of the AI problem itself.

I'm not a big fan of evolutionary methods.

I'm not advocating proceeding primarily with conscious human engineering. At
the moment I'm advocating people think more carefully about how their AI
projects could turn nasty. We all wear rose-tinted glasses with our own
projects, and the future in general, but we're playing with powerful juju
here that deserves more care.
My current thoughts are to have an independant peer intelligence in the
design feedback process, be it human or not. And thorough sandboxing.
If you don't, then what's to stop it self-organising into something simpler
that just copies itself once it thinks up the idea?

Again you underline my concern.

Urgh! Are you equating intelligent design with rule-based AI? - If so, I
don't subscribe to that point of view. Rule-based 'AI' doesn't even qualify
as AI in my view! :P
