At least for the first several years of full dive, motor precision probably isn't going to be perfect and there's going to be software smoothing out errors by making assumptions about normal human movements. That'll work fine for locomotion, head turning, hand gestures, and pointing at or interacting with something that can be snapped to, but the very slight movement differences necessary for typing will probably be hard for a while.
It's likely that what >>347979006 mentions will happen first, and that there'll be a novel interface for transcribing text via thought with no motor control necessary.

But yeah, ultimately it will be about the quality of the tech. I absolutely don't expect the tech to be perfect enough for most work applications within the first few years of consumer availability though.
