I can't disagree with the contents of your comment; I upvoted it. Yes, this work is incremental, not a breakthrough; it's a natural progression from a lot of other prior work. BUT they're doing this with environments (not just with objects), with an agent that explores those environments, with color (unlike some of the older work), and with evident applicability in a range of "Open AI Gym"-style deep RL tasks. I find the examples the authors show amazing. They feel qualitatively different. The fact that the work is incremental doesn't make it any less impressive. BTW, I remember reading that paper from MIT when it came out; I find it also amazing -- even if in the end it's all only "fitting a manifold to a set of points."
