I don't agree with the prediction but I will say that at least in America, we've been overly optimistic about almost everything since world war II. Is particularly painful when you look at the imagination of science fiction versus the reality of science in the realm of say space travel, especially interstellar travel. This imagination effect gets the public behind your new invention in part because it seems to be just the beginning the start of something new. The tip of the iceberg. But sometimes it's really just a tiny bit of ice.
For the record, I'm actually rather bullish on self-driving cars. There's nothing physically impossible about solving the problem, but I'm not surprised it's harder than it sounds. But I don't see humans being fundamentally prevented from solving the problem in the same way that humans are fundamentally prevented from ever engaging in everyday space travel.
