This was a helpful comment. After the article, the question that popped into my head was… so ok should I try and compare this to like BLAS or something like Jax?

But, this sort of language is more about writing and reading from the disk efficiently, right? I guess SIMD type optimizations would be less of a thing.

I think that array languages have historically used memory mapped files for IO, and treat them like a big data frame, but other versions also support streaming IO. Its up to the implementers of the runtime to use SIMD instructions if they deem this optimal but not something you would use yourself.

Personally I think the best comparison would be Python+Pandas/polars+... or R+tidyverse+..., the key thing being there's less need for the "..." in a language with good table manipulation etc built in.
