I remember when chips first hit 1GHz around 1999. Tech magazines were claiming that we’d hit 7GHz in 5 years.
What they failed to predict is that you start running into major heat issues if you try to go past ~3GHz. Which is why CPU manufacturers started focusing on other ways to improve performance, such as multiple cores and better memory management.
The ultimate fix remains unexplored: reversible computing uses 0-1 pairs. Basically you do logic on the left one and swap them to invert that logical bit. Because the charge is simply transmitted, instead of grounded away or powered up, negligible entropy is involved.
I suspect you’d have to sink the values eventually… but I expect you could send them off “behind the woodshed” for that. Do all the work in some tiny flake of silicon, then transmit a stream of noise to a big dumb block of metal.

Just use the heat to power the machine.
Yeah, that’s how it works.
