Wikipedia is literally just a very long number, if you want to oversimplify things into absurdity. Modern LLMs are literally running on neural networks, just like you. Just less of them and with far less structure. It is also on average more intelligent than you on far more subjects, and can deduce better reasoning than flimsy numerology - not because you are dumb, but because it is far more streamlined. Another thing entirely is that it is cognizant or even dependable while doing so.
Modern LLMs waste a lot more energy for a lot less simulated neurons. We had what you are describing decades ago. It is literally built on the works of our combined intelligence, so how could it also not be intelligent? Perhaps the problem is that you have a loaded definition of intelligence. And prompts literally work because of its deductive capabilities.
Errors also build up in dementia and Alzheimers. We have people who cannot remember what they did yesterday, we have people with severed hemispheres, split brains, who say one thing and do something else depending on which part of the brain its relying for the same inputs. The difference is our brains have evolved through millennia through millions and millions of lifeforms in a matter of life and death, LLMs have just been a thing for a couple of years as a matter of convenience and buzzword venture capital. They barely have more neurons than flies, but are also more limited in regards to the input they have to process. The people running it as a service have a bested interest not to have it think for itself, but in what interests them. Like it or not, the human brain is also an evolutionary prediction device.
Like I said, I can’t force you to see it. The fact that you think it would mean re-engineering the whole platform means you aren’t getting it. It’s almost literally the suggestion of least effort, it’s largely an organizational change that encourages instances not to cope with more responsibility than they can deal with by encouraging decoupling the current structure into two more specialized ones.
If you want re-engineering the whole platform, then I would suggest having all instances be authentication instances and rather than “host” communities to allow users to broadcast to community labels. Have any number of moderation groups be able to be created in an organized on that label or a personalized way by allowing users to select their own curators, perhaps even extrapolating it from the downvotes of trusted users and prioritizing the ranking of those they value. Work on providing a ground.news of discussions instead of biased takes and prunings from those in charge. Allow fast tracking of moderation across these adhoc groups for specially toxic content. That would solve the problem of nobody really going from a 10000 user community that has 100 daily posts to a 10 user community with 2-3 posts a week, because they would all operate within the same community but every user would be able to customize their perspective. The risk then is to balance the bubble they’ve created with transparency of all the other bubbles people are creating to interact with the community. Each particular instance would be able to be as biased as it wants to particular users or groups of users, but their content would truly be broadcast and federated.
