I've worked on a lot of old code bases that were built by this previous generation of engineers, and let me tell you, their code was awful. Software engineering has learned a lot over the last decade.

Sure there are some things that aren't emphasised as much but most of them aren't super useful. JavaScript, css, and mobile development are way more useful today than algorithms, cpu pipelines etc...

Most of the last round of unicorns you could build without any of the items you mentioned, but you couldn't even get started without an understanding of modern web or mobile development.

This is coming from someone who is by no means an expert on any of those things but took a bunch of courses on them in college and have only used them a handful of times in the last decade of professional software development to eek out very small performance improvements.
