From what I've read about Mojo it sounds really interesting, but as opposed to the main languages and libraries currently used for machine learning it seems to be proprietary, or am I mistaken? At least, clicking on "Get started with Mojo" on their website seems to lead to a form to fill out instead of to an easy download. I haven't filled it out so I don't know if you need to wait for approval or what. But, given how little I've seen about it in terms of availability and source availability, I guess I'm having a hard time understanding why people seem to be so hyped about it. No matter how nice it is, unless it gives some major advantages over Python and some system like PyTorch or Jax, I wouldn't port my entire machine learning pipeline over to a propriety language for which only one implementation exists that I can't even download without filling out a form.
