I wouldn't call it hermetic in that the many forms of documentation are insanely thorough and accessible - if not well advertised. There is no gate-keeping (from my point of view). New users are welcome. It's easy to learn (for the people for whom reading is not an obstacle).

But yes, no contest that the world has been on a simplicity binge. Python won by pushing simplicity and by having giant software corporations choosing it (and not complaining about the line noise nonsense). If you want to go into programming professionally, for now many years, you need python.

I don't know that I would put Javascript in the same bag. I mean, it's the other way: it looks simple and it isn't.

But python, yes, python won because it looks simple and google pushed it.

Many other languages now have to reckon with the python supremacy. This is not specific to perl / raku. It will take work for anything to replace python.
