Always worth knowing vim if you expect to spend time in the terminal. It's very handy for editing configs on remote machines at the very least.

In general, most things developers use today will be around for a long while still. LLMs will make some of it optional, depending on the kind of things you do, but I learned assembly in college, and even though I never used it, I'm happy I did.

The box will get bigger but you can choose whether it's a blackbox or a clear one. One benefit of learning the innards of things is you're not entirely at the mercy of other devs.
