AI can be a "car for the brain".

Some people dream of "Superintelligence", smarter than human AI that acts like a slave, instead of just killing the pesky idiots and calling it a day.

Obviously, there is a spectrum of possibilities between "Pen and paper", "Computer", "Coding agent", ... and "God-level AI controlling whatever can be controlled simultaneously". As well as between "Lawnmower robot" and "All-purpose Terminator" and so on.

Filling in those dots and deciding where to stop before it gets stupid, that can't be so hard?
