Yeah, he mentions that as a caveat that all the benchmarks are done using own language scripting abilities... no external functions are called.
And indeed, you're right to highlight that no self-respecting python coder won't use efficient external lapack or arpack libraries to do the computationally heavy matrix operations. numpy is nearly fully C-code under the hood with some C++ as well.
Rust can achieve identical assembly and speeds to C. The others are different of course. But hey, why be safe when you can do a null pointer deference and shut down global airlines and banks for a day or so? Lol
