Modular open-sourced the compiler and toolchain on August 18, a week after 1.0 and three years after the original commitment. The strategic reversal is the bigger story: the roadmap now says Mojo "may or may not evolve into a full superset of Python, and it's okay if it doesn't." (simonwillison.net) Willison flags the justification, which is that AI-assisted coding tools already handle Python-to-Mojo migration. That's a real bet: agents replacing language compatibility as a migration path. I don't know if it holds, but it's the first time I've seen a language team make a compatibility decision on that basis.
