Read some stuff about #Mojo today. Looks very interesting. Solving Python's performance gaps (where code can't just call into a high-performance native library) could be a BIG jump for it. Could it even catch Go? Plausible. Rust? No, of course not, that's not the target. But not since Julia have I seen a clean language intended for high performance math code.
That said, Python has another problem besides performance - the 2.x/3.x and continuing incompatibility in syntax, frameworks and libraries.
