I compare this to Vacuum Tubes vs Semiconductors specs. Aren't we somehow reaching limits of semiconductors as well and should look for better alternatives instead? #AskHN
You say it takes a supercomputer to match a brain, but a $1 processor will easily beat a human if the task is to add a bunch of numbers, or even just to carefully do something over and over.
I do think there's some fascinating organic/analog vs digital thing going on. Humans took a weird evolutionary branch, got weirdly smart, and lit the technology bomb. Now it looks like our bioslime will give rise to intelligent machines that won't have our frailties or evolutionary baggage, for whom a thousand years is no big deal, who can actually reach the stars if they want to. Ever more complicated kinds of life, using the previous kind of life as a stepping stone.
