I can see it, maybe I'm hallucinating I dunno.
You don't need a brain implant or even a vote if everyone's influence is limited to such extend that they cant look beyond their self interest - voting is not required.
Direct democracy might be to much of a leap but we may take note of what people think and what ideas and proposals are out there.
You have ideas, you could write them down properly with sources and everything. Who is going to read it? What if you have 20 ideas? What would be the point in doing that? If it is pointless you should stop having ideas. There are countless fun, useful and interesting things to do that all have a point.
Say we all start writing down our poorly thought out ideas. Share our collective political ignorance with the void. If that could be aggregated and combined into something perhaps agreeable or just refutable, then we could at least debunk it and at best consider it.
Everyone can come up with a list of pro's and cons for any topic but if many do we can have the full list and may address the [perceived] misconceptions.
Not use LLM as a middle man (that would put it in charge) but as an aggregator. To construct the questions and answers for a poll for example.
If it works it will become worth having ideas, perhaps even good ideas, perhaps the feedback loop has to run for a while for the good ideas to happen.
Anything is better than pretending to know what the public wants while the public doesn't bother to want anything.
There is also the way we blame the representative for doing the wrong thing. They cant take positions on anything without offending some of their voters. We pretend everything is their idea.
I might be hallucinating, either way it is quite an enjoyable thought.
Of course I know no one will go along with anything until civilization implodes again.
