The idea of FSD is, obviously from the effect of hyping it, enormously attractive. It can't happen now. But in the 1990s, speech recognition that would enable me to dictate this comment in a relatively noisy space was science fiction. Now that we have orders of magnitude more computing power, and much better microphones and associated noise rejection technology, you can blithely dictate messages with reliability that was previously a dream.

Thing is to go from being unable to distinguish pencil from cancel to today's almost magical speech recognition, took 25 years. That might be the same interval it takes to go from mowing down motorcyclists to delivering all the safety and productivity potential of level 5 autonomy.
