Could be that blocked servers aren’t feeding their votes back, but also lemmy instances (and fediverse platforms in general) don’t sync data directly. Instead they all store local copies of posts and comments from various instances.
So when you upvote a post on an instance that isn’t your home instance, your home instance updates the vote count for the post in its own database, not in the database of the instance the post is on.
For your vote to be counted on the other instance, your instance has to syncronize its database with the other one. And this is true for all instances. As such, vote counts on a post can be inaccurate across various lemmy instances depending on how recently any given instance has syncronized its database with the rest of the instances.
Actually we do, the cerebellum is what the neural networks in LLMs were partially based off. It’s essentially a huge collection of input/output modules that the other parts of the brain are wired into which preforms various computations. It also handles motor control for the body and figures out how to do this through reinforcement learning. (The way the reinforcement learning works is different to LLMs though because it’s a biological process) So when you throw a ball, for example, various modules in the cerebellum take in inputs from the visual centers, arm muscles, etc and compute the outputs needed to produce the throwing motion to reach your target.
We also have the cerebrum though, which along with the rest of the brain is the magic voodoo that creates our consciousness and self awareness and we can’t recreate with a computer.
