Realistically, people would build tooling — either free, ad supported, or SaaS-based — that lets the average person synthesize publicly available data. Just making the data available allows motivated individuals / groups to do a lot of the work upfront, and then share the fruits of that work with everyone else, either for free or for a fee.

You see this already today with data from census bureau, FRED databases, COVID tracking tools, think tanks, etc.
