I know I thought that...but I was wrong.

There are these tiny villages in Africa, where people take laptops or tablets and a huge stash of DVDs, and often there isn't even a roof just like 4 sticks poking up from the ground, maybe a tarp above it or possibly not even that. People come from hundreds of miles away, even walking, and they can watch videos from literal Harvard/Yale/etc. professors on whatever subject - engineering, lessions on how to speak English, biology, physics, etc. The barriers for people who truly WANT knowledge are pretty much entirely gone now, world-wide.

Which lasted it seems for about a minute, while instead now, misinformation flows even more freely. Those setups that I mentioned above took DECADES to create, leveraging the technology available at each timepoint, and more than a little prep work to discuss with the recipient culture to let them know it is an option. And even then, situations such as Boco Haram continue to threaten their continuation, bc girls (& women) learning things is considered bad in that case.

Thus, I learned that ignorance is extremely easy to cure (barely an inconvenience, if you know that famous YouTuber's catchphrase;-). Entire courses are available freely online, such as the Crash Course series...of series (US History, World History, literature, biology, chemistry, physics, check it out!), and nowadays the most dumbed-down explanations of extremely complex topics as you could ever want, see e.g. this video.

The barriers nowadays to knowing things are "different". See e.g. the movie WALL-E, where the humans all just gave up and sat down... but then were never able to get back up again.
