Hacker News was full of people somehow assuming progress there would advance linearly, and plainly telling so ("look how much progress we've made in the last 5 years"). Or comparing the problem of autonomous self driving to much, much more solvable problems (plane autopilots: mostly flying straight lines in a featureless void). Though to be fair, there were also always people in the comments who realized the immense complexity of the problem, suspecting that fully autonomous driving might need either massive infrastructure changes (bringing those cars closer to something akin of an autonomous train), or generalized AI.
