I was talking about irreversible classical computers, where Landauer bounds it much much harshly, not quantum computers relying on the much looser Margolus-Levitin limit.
To put this in perspective, there’s a 35 order of magnitude or so difference between what a quantum computer’s limit is and what a classical computer’s limit is.
While the most pessimistic conclusions are probably wrong (I think they will accept the energy cost of 300 watts-5 kilowatts to increase computation by one or 2 orders of magnitude, since intelligence is very valuable and such a thing would lead to a Vernor Vinge-like singularity) this is a nice post for describing the difference.
So it actually supports my post here, since I talked about how quantum/reversible computers would favor the intelligence Explosion story. I am pessimistic on quantum/reversible computers being practical before 2100, which is why the accelerating change story is favored.
So you and me actually agree here, so are we getting confused about something.
And black hole computers are possible, but realistically will be developed post-singularity.
