Musk is overly optimistic and makes marketing claims and predictions about the future. I think Musk's worst estimates could actually be false advertising (e.g. the claims about Autopilot). But in most cases they are understood to be within some bounds of possibility, even if it's a 95th %ile best-case estimate. Milton made fraudulent claims about the existing technology that they had built, which is I think categorically different than most of Musk's futurology. There's no sense in which Milton's claims might be true; they were objectively false statements at the time they were made.
