I agree. I think we elevated Computer Science’s importance early on in the industry, and that has stuck around. If you’re a University researcher trying to make a better compression algorithm or whatever, then yeah you’ve got a lot of overlap with mathematicians. But if you’re out in the industry building CRUD apps to fit some business use case, all that theory isn’t going to matter much in your day to day.
It’s still just one of those mostly-bureaucratic hurdles where you need a CS degree to get your first job, and you need to be good at math to get the CS degree.
That said, there are definitely crucial moments where regular projects can still hit scalability boundaries, and a solid understanding of math and CS fundamentals can get you through that. Every single developer doesn’t need to know that stuff, but it’s occasionally good to have access to somebody who does.
In the end, they both end up learning effectively the same lesson
