True, but the great thinkers and revolutionaries (and artists, architects, etc) don't just happen to flourish in one age on random, they're the result and a part of a massive change in society that provides the right environment in the right moment for a "golden age" to happen. Gutenberg's invention of press was probably one of the biggest triggers of civilization change since the invention of farming, all of the sudden knowledge and information became available and started to flow freely between millions of common people, and between different countries which was super important as traveling was hard and slow and unsafe back then. It was like the Internet of that time.
