It would be cool to be an expert at algorithms, apply them to hard problems, and build cool things. I feel like, for me, there's no point in learning them since the work I get is always "put a button here, update the DB" type stuff.
I remember one time when I realized this: a TV show character suggested building an app that lets you take a picture of someone's shoes and then give you links where you could buy them. It sounded a) like a pretty good business idea and b) crazy hard to build (the time the show aired was before the Deep Learning proliferation iirc).
I do agree that algorithms are fun and the basic ones are probably useful in everyday work, but for anything complicated you'd rather use a proper library. It's also definitely good to have knowledge of their internal workings though.
