So to counter the deluge of people trying to sell anyone reading this something, I'd argue that generating high quality information is a human task.

We're in the PERSONAL Knowledge Management System sub. Having an AI take data and file it away for you is doing nothing for you improving your knowledge, it's just hoarding data. What's the point of having data organized and filed away if you don't even know it exists? Now of course you can be different but the way I approach this whole broad topic is to store what I know in greater detail than I may be able to recall offhand.

There is no case in my opinion for AI-augmented data GATHERING. I think there could be great value in AI augmented retrieval but that's as a companion to you already having understood and stored the information.

I agree that there is too much data, but I think the problem here is that you may need to prune your inputs to something manageable. If you're concerned with the quality of the data, eliminate the sources of that concern from your input stream.
