I think maybe you meant to link to AI Winter (which that link has a link to down at the bottom) as that article doesn't really support your point (that people within AI acknowledge it has hype cycles) at all, there's nothing about AI directly in it, although it does serve a refutation that 'hype cycle' means it'll go away; if that's what you meant your sentence was a bit odd.
the citation is because the only way you could claim ai isn't in a hype cycle at the moment is if you don't know that that's a defined term within tech spaces
