Yes it is, but languages like R, Matlab, Julia, Crystal are also used, and they are all (well xcept for Matlab) superior to Python.

explain?

the author is a huge sjw and made a post on his website that if you support trump you are not allowed to use his software

Julia is actually a slower JIT than Numba. R also has less performance all around than Python. If I had to guess, I'd say that with Guido gone, Python is going to focus much more on performance. I wouldn't be surprised if a JIT replaced the reference CPython implementation in a few years.

Doesn't make the software bad. At least yet.

We all know LuaJIT and TCL rule.

So, is there a verdict on why these people with no prior political background go full sjw unprovoked? Paid? Threathened? Soyed up?

Not really; you can find microbenchmarks that go both ways. It doesn't matter though, because Julia can optimize at scale much better than Numba.

Even the Numba devs admit that their project lags Julia.

protip: Guido is still part of the Python community as a normal community member.

This is off topic, but tcl.tk is beautiful. It's an actual website with minimal bullshit.
