Today's computers were perfectly obvious to Gordon Moore in his 1965 paper. By contrast nobody today is writing papers about the inevitable expansion of carbon-free energy production.
Various forms of next generation nuclear would meet that requirement right? People are certainly writing papers on building better nuclear power plants. Doesn't even have to be something exotic like fusion.
If there is some kind of nuclear power that is millions of times cheaper per unit output than it was in 1965, I am unaware of it.
