I beg to differ that "the technology is here". Everyone I see who uses voice commands have to speak in a very contrived manner so that the computer can understand them properly. Computer vision systems still run into all sorts of weird edge cases.

We've progressed an impressive lot since, say, the nineties when computers (and the internet) started to spread to the general consumer market but the last 10% or so of the way is what would really be the game changer. And if we believe Pareto, of course that is gonna be 90% of the work. We've barely scratched the surface.
