There is a difference between going all the way back to 1995 / reading old documentation vs learning the basics of CS.

This strawman is used in several comments. CS is not "some old knowledge you might never use". Knowing that it's way faster to search by key in a hashmap rather than iterating through a whole array is useful. Knowing why it's a bad practice not to have primary key (and other DB knowledge) is useful. Knowing the stages of a HTTP request is useful.

You can get a job and actually do some productive work without any of that, but that some point not knowing all those basics is going to harm your work.
