By now they should be sitting on a billion dollars that safely yields a forever self-funding annual income ($30m-$50m) that would pay for all of their necessary expenses. They would no longer require any donations. It's grotesque and wildly irresponsible how they're managing the organization. If LLMs become the center of knowledge resources going forward (which they will), Wikipedia's funding will decline as their traffic declines, and they'll collapse into a spiral of cut-backs, as they operate on a present structure that burns most of its financial capability annually (this opens them up to a shock to the system on inflection, which is happening now).
