I know an awful lot about Tesla, electric cars, Toyota and agile technology yes. Clearly more than you.
Tesla changed the world, significantly and pushed electric car development forward by at least 25 years. this is not a disputed fact. Everybody stands on the shoulders of others, that's how it works.
It's putting all the elements together into a thing that works on every aspect, performance, price, accessibility, usability, marketing, infrastructure.
Tesla got all of that right, and changed the world.
SpaceX did it as well.
So did StarLink.
You can not like the guy, up to you - but he has changed the world, a lot for the better.
