I think / hope that Elon Musk wanted everyone to be crystal clear about the end goal from the outset. Go on public record about the ambition in a way that will push himself and his employees. Use language to drive vision and outcome.
I agree that presenting a vision and facing it with reality of what is currently possible is great because it may motivate people to try to achieve something better than they would normally think of.
But misrepresenting the reality as if it already was reflecting the vision, when in fact it is not, bears in my opinion many signs of fraud.
For example, consider someone who has a "vision of wine" and decides to sell bottles of grape juice which are supposed to represent that vision. They can have honest intention to fill those bottles with wine at some point in time. But as far as they in fact sell the grape juice, I think that it is reasonable to require them to clearly present it as such.
