Eye tracking and hand gesture tracking are hardly new, even used in conjunction. The issue is, as pointed out, none do it well (accurately) enough to be of quality use but progress has certainly been made over a few decades. I've not used the new Apple device but I'd be surprised if accuracy is still good enough. I'll be happy to be wrong but I suspect there's still a fair amount if work needed to get us to a point your average user is happy with. We already complain about touch devices like touch screens which are steps above anything current gesture and eye tracking I've seen can currently do (to my knowledge). People still want physical high precision keys, knobs, button and physical devices like controllers. Tactile feedback is part of it but the accuracy/precision is a larger part.
