> CS is sorta useful in writing business systems but really for CS level problems, you’re mostly using installed software, not writing your own RDBMS, or your own sorting algorithm. There are many jobs for which CS is absolutely useless. Or mostly useless. But I'm sure there are also many jobs, where having a foundation in CS could be very helpful in weighing the merits of different solutions to a problem. Big O (scaling), understanding existing implementations, their performance on particular hardware, the difficulty (or non-) of implementing a new technique that doesn't exist as ready-to-use library, language issues, etc, etc. Sure maybe one can do well without diving into CS. But that doesn't take away its value.
