I was thinking something like undeniable or incontrovertible might be more apt to convey the period between something being obvious to an objective observer and when even people who are predisposed to want it to work acknowledge that it doesn’t. The magical thinking around blockchains is a good example where the flaws have been exhaustively discussed but there are enough people who don’t like the traditional banks (understandable) and are hoping that it can work if enough people try really hard.
