Earlier quoted context omitted.
Five years ago people were saying that about both Tesla and SpaceX. "Is he really serious about going into space? The whole thing sounds ludicrous. Even if he reduces the cost 10X, launches are still crazy expensive and have al sorts of strange complications." "Is he really serious about electric cars? The whole thing..." etc.
I dont think its the same at all Have we gont to space before? Yes Have we done electric cars before? Yes Have we solved congestion by increasing the speed of a transport medium? Concorde
But have we improved travel speed and convenience before? Sure: high speed trains, commuter airlines, superhighways, etc. And, maybe one day, Hyperloop?
