> We have mechanical muscles, and the human strength that was needed before the industrial revolution is no longer important; weight lifters still strength train, but it's a hobby, and nobody needs to do it.

The amount of strength required for the median job may have decreased, but that doesn't mean that nobody needs to do it. The health ramifications of not strength training are constant, and the same can be said for using (or not using) our brains.

You can say that, but check how many people are going to the gym regularly, let alone training up to the standard of strength of an average manual laborer from before the industrial revolution.

If AI fills its promise, some people will be telling others they should think more, but people will get lazy.

I'm specifically calling out the wording "nobody needs to do it." That is patently false.

		If AI fulfills its promise and we get superintelligence, humans will not be capable of contributing anything of economic value via thought, possibly outside of small, comstrained niches. You may as well try to outlift a crane. Either this whole AI thing fails, and we never make the last small number of breakthroughs (or scaling) that gets us intelligent machines, or the obsolescence of the human brain is inevitable. I'm betting that machines are going to end up intelligent, at least in the moderate future.
