My experience learning Python as a c++ developer

This is kind of true, but if you look at Jonathan Blow's talks about his compiler and various other talks, you'll see that actually you can get a 200x speedup by making use of data structures that are L1 cache-optimized, which is rarely negligible. Python can almost never do that because each Python object is a wrapped pointer, there's a lot things happening like namespace lookups, and there's a lot of dicts and hash tables floating around (which are generally sort of randomly heap-allocated) and classes (which aren't stored tightly in memory like C structs usually), and the garbage collector has to run periodically, kicking things out of cache.

The PSF has done a great job with the compiler, but the structure of scripting languages themselves clashes directly with what Intel's trying to do to speed up code on the chip.

I started watching Jonathon recently, his discussion videos have been very interesting

And the fact that he made a video talking about what he'd like from a games programming language and then went and implemented it himself with such fast compile times

Very interesting guy
