> Mojo lang seems to be targeting, but I rarely hear about it here

Momentum over at Mojo lang seems very very slow.

According to their roadmap, they're still busy on Phase 1 ("High performance CPU + GPU coding"), and haven't touched Phase 2 ("Systems application programming") and Phase 3 ("Dynamic object-oriented programming").

So perhaps there isn't much to talk about?

They've got a lot of work yet to do to be a general purpose language, but for GPU programming they have already demonstrated that they can outperform CUDA on Nvidia GPUs.

That's pretty compelling.
