People should really avoid the hype in most cases, mojo is basically its own language right now despite its "python superset" marketing bs. It's vaguely like python except for: no classes, no list/dict comprehensions, no lamba functions, tuples are messed up, no global variables, variable capturing scopes are not what you'd expect, no yield/generators, no async for/async with, etc. There's a long list of common python features it doesn't support. In addition, it's closed source and "sign up for access". This thing is the next V in my opinion.
