I have not the vaguest idea of what you mean by "sentience". I am still
proposing reflectivity - superhuman reflectivity, in fact. Why are you so
horrified at my proposing to omit something if you do not know what you
mean by the term, let alone what I mean by it?

Yes, saving the world is significantly more difficult than blowing it up.
I would rise to the challenge, raise the level of my game sufficiently to
change the default destiny of a seed AI researcher, rather than walking
into the whirling razor blades of which I was once ignorant. I understand
if you decide that the challenge is beyond you, for yes, it is difficult.
But it is harder to understand why you are still on the playing field,
endangering yourself and others.

Again, I've got no clue what you mean by 'non-sentient'. I was still
planning on using recursive self-improvement, self-modification, total
self-access or "autopotence" in Nick Bostrom's phrase, full reflectivity,

Not from nothing. Plenty of precedents, even if they are not widely known.

Does that mean that you'll create something without understanding how it
works? Whirling razor blades, here we come.

By "sentient AGI" you mean recursive self-improvement thrown together at
random, which of course will be sentient whatever that means, because
humans are sentient therefore so must be an AGI? Or is sentience just this
holy and mysterious power that you don't know how it works, but you think
it is important, so I'm committing blasphemy by suggesting that I not
include it, whatever it is?
Seriously, I don't see how anyone can make this huge fuss over sentience in
AGI when you don't know how it works and you can't give me a walkthrough of
how it produces useful outputs. I have a few small ideas about
half-understood architectural quirks that give humans the belief they are
conscious, architectural quirks to which I applied the term "sentience".
Evidently this was a huge mistake. I hereby announce my intent to build

Maybe that's what you'd do in my shoes. My brilliant new notion is to
understand what I am doing, rather than randomly guessing, and see if that
lets me finish my work before the meddling dabblers blow up the world by
accident. Though in your case it does begin to border on being on purpose.
"Sentient", "non-sentient", this is phlogiston, Greek philosophy. You
cannot argue about something you do not understand, mystical substances and
mystical properties of mystical systems. I intend to unravel the sacred
mystery of flooginess, which I have already come far enough to declare as a
non-mysterious target. Then, having unravelled it, I will either know how
to build a non-floogly optimization process, or I will know in detail why
floogling is necessary. I am only announcing my moral preference in favor
of non-floogly optimization processes. I won't definitely say it's
possible or impossible until I know in more detail where the present
confusion comes from, and I certainly don't intend to make up campfire
stories about the mystical powers of floogly systems until I can do a
walkthrough of how they work. Do a walkthrough, not tell stories about
them. As far as I can guess, the whole thing will turn out to be a
confusion, probably a very interesting confusion, but a confusion nonetheless.
