Extrapolate the flight time from NYC to London in 1976 ... have you seen the J-curve? Or extrapolate the curve for self driving cars once they were only "two years away". Catch is, tech progress is not one curve. It's overlapping S curves, stair steps of progress and stagnation, with the next iteration starting off worse than the current one, until crossing it as the current one tops out.
