The problem is - can the potential ever be realised? Self-driving cars are, what, 90% of the way there? And have basically been stuck at "almost there" for quite some time. AR had huge potential when I first played with it in the early 2000s. Still basically nowhere. So we've now got systems which can generate text which fools people into thinking it was written by a human - well, Eliza got there first. Text to speech? The Voder was doing that in 1939! This stuff is better, sure, but pretty far from being realistic. Perhaps this will succeed. But potential doesn't always mean achievable.
