The advent of thinking machines only replaces human thinking if humans choose to stop thinking.

Sure, humans will be sitting at home unemployed with plenty of time to think. They just won't be doing any thinking that has much of an affect on the world or their situation.

Unless the whole paradigm shifts and we value caring about our neighbours whoever they might be. Do what people do best, make a village.

It doesn't have to imply replacement. Do you stop thinking just because other humans can?

Looking at reality TV, I think people may have stopped thinking.

To add to others, thinking was never only a human act

But no other species were fed up with thinking as much as humans to come up with this brilliant way to commit mental suicide by succumbing to their own brainchild.

What's super cringe is that there already was a company called Thinking Machines, which built the Connection Machine supercomputer. The CM was featured in the movie Jurassic Park and had a network fabric for its CPUs co-designed by Richard Feynman.

This is yet another techbro outfit (although founded by a techsis) necromancing the name of the former supercomputer company. It's as if OpenAI decided to call itself Symbolics for the associations with that name.
