A big difference how? You could work for the NSA and make it easier for the government to know people's thoughts, that would sure make a big difference in the world. Or you could build an information sharing and vetting platform which could use proofs from multiple independent sources to certify data as true by tying it to factual evidence, a kind of scientific reddit to combat disinformation. You could use it as a backend to Wikipedia to vet and prove information, or disprove. Extend it using multiple dependent proofs to support another and you might be able to provide a platform on which to fight for political issues based on reams of certified data. Also, jobs. It's hard to give some people jobs. People need jobs, and they need to make money, in order to fuel an economy and sustain a society. As an example, in a country with some 6 million felons, it's hard for them to get jobs, so they become a strain on the economy (among other things). Make a thing that helps people who have a hard time getting a job to get a job.
