Don't buy it.

A decent OCaml version of a C or Zig compiler would almost certainly not be 10x slower. And it would be significantly easier to parallelize without introducing bugs so it might even be quite a bit faster on big codebases.

Actually designing your programming language to be processed quickly (can definitively figure things out with local parsing, minimizing the number of files that need to be touched, etc.) is WAY more important than the low-level implementation for overall compilation speed.

And I suspect that the author would have gotten a lot further had he been using a GC language and not had to deal with all the low-level issues and debugging.

I like Zig, and I use it a lot. But it is NOT my general purpose language. I'm definitely going to reach for Python first unless I absolutely know that I'm going to be doing systems programming. Python (or anything garbage collected with solid libraries) simply is way more productive on short time scales for small codebases.
