I have my doubts with Jai, the fact that Blow & co seems to have major misunderstandings with regards to RAII doesn't lend much confidence.

Also a 19,000 line C++ program(this is tiny) does not take 45 minutes unless something is seriously broken, it should be a few seconds at most for full rebuild even with a decent amount of template usage. This makes me suspect this author doesn't have much C++ experience, as this should have been obvious to them.

I do like the build script being in the same language, CMake can just die.

The metaprogramming looks more confusing than C++, why is "sin"/"cos" a string?

Based on this article I'm not sure what Jai's strength is, I would have assumed metaprogramming and SIMD prior, but these are hardly discussed, and the bit on metaprogramming didn't make much sense to me.

There is no RAII in his language. Why would you care if he understands it or not?

What an odd take. It is like saying: there is no addition semantic in his language, why would you care if he understands it or not?

This take is equally bizarre. Most languages have an addition semantic. Most languages do not have RAII. That's, by and large, a C++ thing. Jai does NOT have RAII. So, again, why would anybody care what his opinion on RAII is?
