Mojo is just like Crystal and a dozen other predecessors that pretend to imitate the syntax of an existing dynamic language like Python or Ruby and provide some more performance and no other benefit of importance. That has never been enough.

Mojo is still quite far in vaporware land as far as Python compatibility goes, but they do claim to target much higher level of compatibility than eg Crystal.

[Daishiman]

People want bug-for-bug compatibility when switching costs are high, and that never works out in practice.

An alternative language has to be far superior to its alternatives to justify the switching costs.

In fairness, it worked (quite well) for Typescript.
