> I suspect you are unfamiliar with the GIL in python.

Sadly, I’m deeply familiar. What made Evan Phoenix’s Rubinius work so exciting in ~2012 was getting rid of the GIL and seeing what was “fixed” by parallelism and what was not.

You make a good point. I didn’t read the parent comment that way but you’re right about how you scale python with the GIL vs JVM.
