If you truly believe you can get a pony, you’ll get a pony. Every other developed nation on Earth has a pony, so, by God, we can get one too!
Like how Elon Musk says that hydrogen fuel cells are dumb. He’s expected to say that, since he’s building a Gigafactory, not to mention maybe multiple Gigafactories in the future. His opinion here should be taken with a heap of salt.
In my opinion, it depends on the person. Elon Musk’s SpaceX and Tesla were even mentioned in the beginning of this article, as being started with a sole founder. However, Musk is known for his perseverance, and especially for his 100+ hour workweeks; so, as ‘they’ (might) say, “fuel economy may vary”.
