Agree here. Not quite, actually, because nanotechnology could introduce
a substrate that actually restructures itself adaptively, dynamically.
For instance, one could implement some rarely changing control circuits
in bucky circuitry, which would be more efficient than computronium
for that specific, rarely but changing task.

I'm kinda missing the word "speed" here.

Hmm. Reasonable as to "number of bits" and "speed of tweakage of said bits",
yes. Silicon does imply photolithography, and photolithography does
imply a certain structure size, flatland, and Moore saturating on that
substrate in about a decade.
So, I disagree with the silicon part of "reasonable piece of silicon".
I would rather use the more neutral word "substrate".

Yes, but an AI which takes a MYear to say "Hello, world!" is perhaps not
very recognizable as an AI, especially given that you can't assess the
AIness of a precursor, if it's impractically slooooowwwwwwwwwwwwwwwwwwwwwwwwwww.
If I want to replay one GYear of evolution in practical time, I obviously need
something which is a great deal faster than realtime.

Basically, you don't balance very much, for most current purposes hardware
is a constant. If you want the most of crunch these days it means investing
in air conditioning and a hall full of PCs, and a large number of fat switches.

Speed, of course. That was easy.
