We're in this nadir between self-driving horses and self-driving cars; future generations will look back on us and say «well sure maybe their cars didn't drive themselves, but at least they could majestically leap over obstacles just like ours do!» and then they'll say «what's that?» and then they'll say «they didn't?» and then they'll say «haha WOW, no wonder nobody ever travels to the past.»
