CEO can use it on Elon to keep him placated
This often works to his advantages; the 'always believe' are loud.
1. didn't know what he was talking about
2. was over-optimistic about timelines to the point that there would be very little difference if it were a lie
3. objectively lied on purpose in order to further self interests
4. exaggerated or over-promised more than could be attributed to salesmanship
5. flip-flopped and refused to acknowledge the change in stance
6. stated things entirely to be vindictive, and let the truth of the statements be irrelevant
The problem isn't that people 'never believe', the problem is 'whatever is said should be suspect to the point that if it is actually true then that is entirely a side-effect of the statement and not the point of it'.
You seem to be unaware or Elon time or how Elon has made predictions in the past, generally not that "this will happen by date X" but that "this cannot possibly happen _before_ date X". Which are very different statements.
There is a contingent of people who want to retcon any statement ever to paint Elon as a fraud, when reality is much too subtle for trivial blanket labels like you want to apply.
At this point, there are shades of him being E Lon Hubbard to the remaining believers; for most of them it seems totally unshakeable.
(Humanity was extremely fortunate that the existence of L Ron Hubbard and the existence of the Internet did not significantly overlap.)
Which, as I recall, he tried but the courts said 'no'.
How many times have Trump been caught lying or doing a 180 from one day to the next? And there are still tons of people believing him.
I'm honestly surprised that anyone on HN wouldn't understand this.
Maybe I'm overthinking it and this is just a rhetorical gotcha.
After all, there's definitely no market for a product that has been finely-trained on social media posts to the point where it can perfectly ape social media posts. There's no money for Twitter to make there, so the technology it produces from this analysis shall certainly never find its way into spam bots that create content indistinguishable from genuine humans on Twitter.
