A few problems with this Fable's project: 1. It's not Python by any means, it's a subset with its own runtime, its own quirks and nuances; 2. It will be impossible to maintain parity with CPython without AI assistance; 3. It will die the same way as dozens of similar (even non-AI projects) died before, and reasons will be the same: (1) and (2).
A subset of python is python. Half a tomato is still tomato
>2. It will be impossible to maintain parity with CPython without AI assistance
What does that even mean? If you would have said that it's impossible to update to python 3.15 of further, I'd get it.
