I own a few shares of Tesla, because I know there is hype and because I want a world where ICE autos is an option and not a foregone conclusion.

I see this (and to an extent, my interest in Tesla) as a “rising tide lifts all boats” sort of situation. Anyone differentiating their automobiles by making batteries at a noteworthy price point pushes everybody else to at least try to match. The gauntlet is thrown down.

I really care if SpaceX succeeds. I only care that Tesla succeeds enough to be a model worth improving upon. If they go down as a cautionary tale against making electric cars that would be bad for everybody.
