I can't see why it's relevant. We're talking about Uber's bet on self-driving cars and this person commented with an bitter, offtopic gripe about how they think HN commenters are losers.

You copy pasted something you were about to write on Reddit?

I don't know which part you mean, so you might have to clarify. But I don't think they were lying about having a self-driving car program - as someone else mentioned there was a pretty famous lawsuit about this very topic. I don't really remember much about how far along they claimed to be, but it's definitely possible they exaggerated how successful their efforts were - so that could be construed as lying I guess? But it's a tough nut to crack, as evidenced by Tesla's ongoing FSD problems.

It was ... over-optimistic.

I would -suspect- that we'll get full self driving -eventually-, but which of the companies attempting it will succeed first and how many years from now I have no idea.
