I think we’re still ahead - the internet has provided a lot of new learning opportunities. When I was a kid in the 90s I explored Encyclopedia Encarta - if I’d had access to Wikipedia it’d have been many times richer.
Considering that knowledge and technology accumulate I think it’d be hard to find a time where enlightenment has decreased at a global level - local examples are depressingly common though… Afghanistan in the 60s and 70s was far more enlightened than it is today. If you’re unfamiliar with what’s happened to the country please feel free to enjoy an extremely depressing afternoon of enlightenment courtesy of the internet - you could also watch The Kite Runner.
