Well all I'll say is...
There was a time when I thought slide film was dead, but then came Ektachrome. There was a time when I thought new scanners were extremely unlikely, but we have multiple lab grade scanners hitting the marketing in the next year. There was a time when I thought processing equipment would be relying solely on old stock that we maintain, but now we have Colenta among a few others. Nobody was supposed to be willing to do the R&D to make new color negative film, but now we have Lucky and Harman going for it. There was a time when new film cameras were a fantasy, but I have a new Pentax 17, Rollei 35AF sitting on my desk. Lomo seems to be making a very attractive new P&S with manual override now. The list goes on... Who would have said we could still buy new 8x10 instant film materials in 2025 from a company that technically isn't even really Polaroid?
Maybe 'Cibachrome' in the way it existed back then is dead, but I'm guessing someone could formulate a new direct positive color material. It would be sad to not have that incredible glossy look and permanence of course. But I'm not a chemist, maybe someone can figure it out.
