logic, computational complexity, algorithms, best practices and patterns one can learn on its own but it's _rare_ to find a self taught coder that has had exposure to these topics.

there are great developer that are self taught and self sufficient, sure, but the majority end up coding small potatoes or cogs within a soul crushing enterprise with zero agency

and while most cs grad have little coding skill they have the ability to learn far beyond because while they don't know the hows, they know whys

so even if their core skill stars similar, their long term trajectories are wildly different, which is something to consider too
