I kinda regret adding the note about performance, because switching to a lower level language used to yield orders of magnitude more performance, but optimizers have evolved and today there's not much difference. Sometimes the higher level language will be even faster because of optimizations. And bad performance is often not to blame on the language, instead blame the programmer or more likely the business people as they think it's great to waste resources as it gives them an excuse to charge more.

If this were true, you'd expect see a lot more native python and the like.

Python is interpreted so super optimizing compilers, SIMD auto vectorization and other recent goodies necessary to get that performance won't work.

Python is not always interpreted. And when it isn't, it's still slow.
