Kernels now written in Mojo were all in hand written in MLIR like in this repo. They made a full language because that's not scalable, a sane language is totally worth it. Nvidia will probably end up buying them in a few years.

NVidia is perfectly fine with C++ and Python JIT.

CUDA Tile was exactly designed to give parity to Python in writing CUDA kernels, acknowledging the relevance of Python, while offering a path researchers don't need to mess with C++.

It was announced at this years GTC.

NVidia has no reason to use Mojo.

I don't think Nvidia would acquire Mojo when the Triton compiler is open source, optimized for Nvidia hardware and considered a industry standard.

Nobody is writing MLIR by hand, what are you on about? There are so many MLIR frontends
