Why would you call your company Thinking Machines if you believe this, by calling them that you're already framing them as replacing the human act of thinking.
Feels like they appropriated the name first, then pivoted ideologically to differentiate themselves from everyone else.
It doesn't have to imply replacement. Do you stop thinking just because other humans can?
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.
The advent of thinking machines only replaces human thinking if humans choose to stop thinking.
