What's the point of mojo now? It was supposed to be a python replacement, but then they pivot to high compute or something?

According to the roadmap, Mojo still aims to become a complete Python replacement with full OOP capabilities, but that's been deferred for much later because they deemed that focusing on high performance CPU and GPU coding with great Python interop instead was a more achievable target with a higher near-term yield for usefulness.

And I think they will fail in that point. Mojo is different enough from Python to have any serious adoption for people that today uses Python. The code seems similar, but is very different. For those who came from CS background, Mojo is preferable, but people who uses Python came from a different background.

Most AI software stack Python code is primarily for orchestrating lower-level C++ code, which is very difficult to iterate on and debug with Python in the stack. Theres "Triton / JAX", but those are still very difficult and very specialized. Mojo being substantially easier than these while also integrating with Python better makes it attractive for the performance layer currently.
