See, you're again projecting things.
Yes, you can do good things with shitty tools. And you could stop and say: this is enough. But then we would probably never have any programming languages at all.
Haskell exists because idiots that made existing languages didn't make one as good as in Philip Wadler's brain.
Go literally exists because idiots cannot use programming languages created by geniuses.
Rust exists because idiots who made all the existing languages didn't make one as good as in Graydon Hoare's brain. After all, all browsers on the market were built in C/C++, who is he to think that he could create a better/different language? Shut up and get on with the program.
C# exists because idiots who created other languages didn't create a language Microsoft wanted to control, and also weren't as good as the one Anders Hejlsberg's brain. After all, Java was already there.
Except Java exists only because who created other languages didn't create a language as good as the one in James Gosling's (and Mike Sheridan's and Patrick Naughton's) brain. Again, C/C++ had already been there, they could've used that.
Is Blow abrasive and shits on a lot of things? Of course. If you can't see past that to what he's actually doing with the language he's implementing, it's your problem.
> Only JB is arrogant to think that only a new language is good enough for him to make a game with.
Lol. I think this is the textbook definition of projection. He literally never said nor implied this in any way, shape, or form.
If anything, creating a new language set him back several years.
