I couldn't agree more. Popularity matters because of training data availability, not that a language is pleasant to write. It means Python probably still has a long life ahead of it, but newcomers have a much higher barrier to entry.

It seems quite plausible that a well written language spec and fewer examples will give the model enough to work with.
The ecosystem matters.
It could be a great way to build out rapidly with low cost, especially if you can get a mapping from another, broader language, to your own.
But even if it were, it's more about design and not sure that a machine will have the same empathy towards a human cognitive shortcomings.
