You have it backwards.
The Musk strategy is to quietly drop failures/broken promises from a previous hype cycle after kicking off a brand new hype cycle to take its place.
This is entirely consistent with his tried and true strategy to constantly redirect attention forward to the distant future, and never stay idle long enough to encourage looking back at the ever growing pile of ideas that didn't work out.
Aw yes, I have it backwards, because I was thinking of the public.
And this strategy isnt Musks. Hes copying politicians and government. It's a very old strategy. Someone even wrote a song about it.
