I do think there's also just a sort of natural goal-post moving when you're talking about something that's hard to imagine. The best comparison in my mind is CGI in movies. When you've never seen something like the Matrix or Lord of the Rings or even Polar Express before, it's wild, but the more you see and sit with it, the more the stuff that isn't right stands out to you. It doesn't mean it's not impressive, but it's hard to describe what isn't realistic about something until you see it. A technology getting things 90% right may still be wrong enough to be noticeable to people, but it's not like you could predict what the 10% that's wrong will be until you try it, and competing technologies may not have the same 10% that's wrong.
