Truth exists by a simple proof by contradiction. * truth does not exist * If truth does not exist, anything and everything is false * If everything is false, so is the statement "truth does not exist" * Therefore truth must exist We're also talking about two questions: does objective reality exist? and can it be accurately communicated (at least up to a certain standard) with human language? I think the first question is not that interesting in most cases, since it devolves into untestable speculation. The second question has gained prominence thanks to postmodernism and can be discussed at length, although ultimately because it aims to deconstruct meaning, it suffers from the same type of contradiction mentioned above... if nothing has meaning, neither does the theory that points that out. That said, neither of these should be relevant in the advent of generative AI and AGI. The fact some tools will produce content that is indistinguishable from reality has no impact on objective reality and whether or not we can capture true statements with language. Not only that, but I think AGI will probably need to grapple with the same problem. I can imagine a super intelligent machine making some advancements in this area, and I suspect it will also hit a wall and realize the limits of its own perceptions.
