> The former is so sick of C++ he's making his own programming language,
This has happened pretty regularly for decades at this point, people hate on c++ and think they have the silver bullet approach to do things better. They spend a few years on it, and it fails to get much traction.
There is a network effect around c++, sure. But industry standards are there for reasons, and usually most of them have a core at least that is sensible. People keep coming back to c++ mostly because it works, and it turns out often if you start with a safer and cleaner language you get 80% of the way there much faster, but a lot of the 20% that's left over is performance related and you just can't get there no matter how hard you try.
So from a business point of view, the pain level of c++ (and associated costs) is somewhat known, but most other approaches trade that off against project risks people just aren't willing to take.
It's not inherently crazy, even in 2021 to start a new high performance project in c++. Obviously the exact requirements matter, but there is a subset of what it can do that we don't really have a obviously good replacement for. What would be crazy is starting a new project in it that doesn't really need any of thee things it's good at.
