> This hasn't been true in a lot of companies for like my entire career. You can move up as an ic.
You can, but it's a dead end ultimately. I've been a distinguished engineer which is about as far as one can go (some companies have Fellows, but it's just a few people so basically impossible). If you have any desire to grow beyond that, management track is the only possibility.
Also, moving to management from a DE level is harder because you're basically around a Sr.Director level (give or take, depending on company) but have no management experience.
If you care about career growth (and I'm not saying you have to, geeking out on the IC ladder is way more fun), I suggest as soon as you are at the equivalent level of a manager on the numeric ladder, switch to management.
