You're projecting the future. It fundamentally cannot be factual. It's a guess. Some guesses (that LLMs are a deeply flawed technology) come from a place of understanding how shit works that other guesses (LLMs are magic) don't, but the actual future impact of the tech inherently must be an opinion, regardless of how well informed it is. There is no objective truth.
(All of this is without the fact that very little of the past is super concrete either. We know specific things happened with relatively high certainty, but why is, again, always a guess.)
