A bonus of the 21st century is that it is easy and inexpensive to get in the top 1% for knowledge on a given topic. In a year, you can see more theatre/serious cinema than 99% of people will see in their lifetimes. You can just choose a topic and download and read every policy paper, every piece of legislation, all codes of practice, court decisions, reviews, etc and can read through them in a couple of months. For a small fee, Jeff Bezos will send you a dozen serious books on any subject which will leave you better informed than almost everyone in your national legislature. This is true for basically every topic outside the hard sciences (where you need a lot of background knowledge to really grapple with things like protein folding and quantum dots). You might not be an expert in the truest sense of the word but given that the number of actual experts on a topics can vary between a few hundred to a dozen, you will be more knowledgeable than almost anyone you ever meet.
