That is implying that we haven’t actually found the problems for it to solve yet, which would make it a solution in search of a problem where PG is optimistic about the outcome of the search.

What I think he is trying to say is that it is a solution that addresses a broad range of problems that are clear now but weren’t envisioned by its creators, which is both impossible given the early claims (its creators already billed it as a general solution with easentially no limits) and, even if you ignore those claims and reduce it to a question of it being broadly applicable as a solution, generally premature (most of the more specific things it is billed as a solution for it hasn’t solved, though some people might have ideas, not yet proven jn practice, of how it can be a component of a solution).
