ML needs a new programming language – Interview with Chris Lattner

When I was young, I enjoyed messing around with new languages, but as time went on, I realized that there is really very little to be gained through new languages that can not be obtained through a new library, without the massive downside of throwing away most of the ecosystem due to incompatibility. Also, CuPy, Triton and Numba already exist right now and are somewhat mature, at least compared to Mojo.

If a learning a new language didn't change how you think about programming, it wasn't a language worth learning.
