I think we're around stage 4 of:

  1.  Elon is a genius, a real world Tony Stark.
  2.  How dare you!  You're just jealous!
  3.  Ok, regardless, he's done more to advance EVe and space travel than anyone else alive.
  4.  Oh God, he's going to cripple US development of EVs and rockets, isn't he?
  5.  Eh, Mars was never happening in my lifetime anyway.

I think he's genuinely changed for the worse, quite a lot, in the last 10 years. Staring down failure seemed to keep the worst tendencies in check, being untouchable amplified them.
