If that's really true, then Webmind is within a couple of years of doing a
hard takeoff. You should have had an FAI-1 system right from the
beginning, will need an FAI-2 system for 1.0 of the AI Engine, and will
need a complete, structurally conforming system *before* you get Webmind
to read a single piece of Java code, since in your description there's at
least the theoretical possibility that Webmind can do a hard takeoff
directly from there.
It so happens that I think the bar is higher and that considerably more
general intelligence is needed first. I'm just saying that, if I believed
what you believe about Webmind, I would be, literally, living in fear.
Genuine, adrenaline-edged fear. I'm nervous now because you know more
about Webmind than I do.

Yes, we need to finish our conversation there. If you're interested in
trying to carry it on SL4:
A --> B (direct cause)
and A --> C (direct cause)
implies observe B ==> observe C (prediction)
but not do B ~~> get C (manipulation)
As far as I can tell, the current Webmind doesn't distinguish between
indirect linkages that are useful for prediction and direct linkages that
are useful for manipulation. If so, it seems to me that Webmind would not
use different representations for "B --> C, B ~~> C" and "A --> B, A -->
C, B ==> C".

Well, it has to be the *right* kind of probabilism - there are four
subpatterns to the design pattern of external reference semantics. I
mean, what kind of information is used to adjust the probabilities?

Uh-huh. So, Ben, did you make your airline flight from the Foresight
Forget about whether you desperately need it yet. Do it because you can.
Say to yourself: "Hey, I can build in this Friendliness feature!"

Are you going to tell me that a belief "I'd give myself a
Friendliness-topped goal system if I had the chance" is also delusion?
