Maybe some history will help here too. In the 90s, the data model of most programming languages wasnt even array-of-structs, but array-of-pointers to otehr pointers to other pointers...

And the majority of software we've inherited is written this way.

In the 90s this didnt matter, since dereferencing a pointer was comparably expensive to arithmetical operations. But with modern CPUs with massive caches and more native parallelisation, the difference is dramatic.

So, even now, the majority of languages we're using; and almost all code we've inherited today, are as far away as you can get from efficiently using modern CPUs.

The task is first to change all these languages to enable ergonomic programming without tons of indirection -- we're very far away from even providing basic tools for performant code
