If they do eventually be the first then all is forgiven (i.e. Fritz Haber is known for the Haber-Bosch process, and not for inventing mustard gas). If they don't, they'll slowly fade into irrelevancy and they'll end up as an MBA case study in 50 years.
If they're a company that seem the closest to solving the biggest problem in using auto-motives and you're a razor-sharp freshly graduated engineer, wouldn't you want to be on that train with ideas that you will actually significantly contribute to self-driving vehicles instead of...increasing Google's/Meta's Ad Revenue?
I'm not defending Tesla's approach, but interested if there's a bit more reasoning behind the inconsistency in the claims ("we're one year away, you better join us to matter!") and not just capitalism gone wild?
