Those levels bake in the expectation of "codez real gud" at FAANG/MANGA/whatever style tech companies since the technical complexity of their operations is high and a high skill bar needs to be hurdled over to contribute to most of those codebases and make impact at the scale they operate at.

One's ability to reverse a binary tree (which is a BS filter, but it is what it is) hasn't been an indicator of ability in some time. What _is_ though, is the wherewithall to understand _when_ that's important and tradeoffs that come with doing that versus using other data structures or systems (in the macro).

My concern is that, assuming today's trajectory of AI services and tooling, the need to understand these fundamentals will become less important over time as the value of "code" as a concept decreases. In a world where prompting is cheap because AI is writing all the code and code no longer matters, then, realistically, tech will be treated even more aggressively as a line item to optimize.

This is a sad reality for people like me whose love for computers and programming got them into this career. Tech has been a great way to make a wonderful living for a long time, and it's unfortunate that we're robbing future generations of what we took for granted.
