The main downside is that usually I only choose languages that the LLM is extremely good at. (however I avoid dynamically typed).

But I hope they succeed, it's a very interesting approach. Then I will jump on it later on. S

The premise of Mojo used to be that it was a superset of Python so in theory LLMs would benefit from that but I'm not sure how much divergence there's been

Are there any benchmarks on which languages models perform best?
