Couple decades in with some leading but still remaining an IC officially.
The right work just doesn't get done without staff engineers and architect types having frequent conversations & meetings as well as constant code reviewing. Or long-term ICs effectively doing this role without the title and expectations/responsibilities (raises hand). You can identify these people because they ask questions relentlessly. Always well-considered ones, but even the ones that might make them look stupid in a meeting.
Coding is a small percentage of the work but also just as important. That's the sweet spot. The "non-stop meetings/socializing" people and the "headphones on & grind PRs" types are both two extremes of behavior that are boat-anchors in any organization and will bring productivity/customer-impact to a screeching halt if it goes unchecked for long enough.
And it's _always_ those stupid-seeming questions that uncover showstopping problems that would have bit you if left ignored.
Edit: Not to greenlight anything Palantir is doing, but in my opinion the FDE/FDSE model is probably everyone's near-future if your company is B2B. You can't be an "ignore meetings" type of person and do that.
