Except escalators never merely become stairs; they are blocked off, torn apart, and under maintenance, making them unusable for weeks at a time here in Massachusetts -- presumably because a malfunctioning escalator could be seriously dangerous.
Having a usable fallback to smart tech's smartness is nice, but it can propose complications (and dangers) the manufacturer doesn't want to deal with because making the gear to deal with them then becomes cost prohibitive. The best thing is dumb tech, to which smartness can be added if desired by the user.
