i'm similarly baffled... but this is what elon says 'I think it's worth noting that when somebody has a breakthrough innovation it is rarely one little thing. Very rarely is it one little thing. It's usually a whole bunch of things that collectively amount to a huge innovation. But the problem is because it's hard to convey a complicated thing to people the innovator or the innovator's PR department will say such and such is the reason why it's better. This little catch phrase. Like what was it with ebay, Pam wants to do Beanie Babies or something. I mean really, that's not the basis of ebay. Oh right, yeah pes dispenser. It's like something the PR department made up. So really innovation is a collection of complex things which are usually difficult to convey so there is some soundbite that's given. You know why's South-West Airlines the most popular Airline in the whole business. It's not just because they use 737s. I mean if it was that easy everybody could do it.' https://www.youtube.com/watch?v=Xohhz9Hn8p0
