I (vaguely) think what the Mojo guys' goal is makes a lot of sense. And I understand why they thought Python was the way to start.

But I just think Python is not the right language to try to turn into this super-optimized parallel processing system they are trying to build.

But their target market are Python programmers, I guess. So I'm not sure what a better option would be.

It would be interesting for them to develop their own language and make it all work. But "yet another programming language" is a tough sell.

cactusfrog•1h ago

What language do you think they should have based Mojo off of? I think Python syntax is great for tensor manipulation.

Except by all accounts they succeeded. I believe they have the fastest matmul on nvidia chips in the industry

timmg•35m ago

I was under the impression that their uptake it slow or non-existant. Am I wrong on that?

ozgrakkurt•24m ago

Is it really faster than cublas?

ziofill•33m ago

Exactly, the idea of not having to learn yet a new language is very compelling

behnamoh•34m ago

signing up to try a programming language (Mojo) is as bad as logging in to your terminal before using it (Warp).

I like Chris Lattner but the ship sailed for a deep learning DSL in like 2012. Mojo is never going to be anything but a vanity project.
