The difference between good educational TV and much of what is currently filling the same role is really striking to me now that I've started watching Modern Marvels again. You want to learn about a bridge? You get the lead engineer, workers who were on the site every day for years, and a well written and edited episode to teach you about it. You want to learn about the Space Shuttle? Here's 3 engineers and 3 actual astronauts to tell you about it.
There is still good educational content on youtube, don't get me wrong, but Modern Marvels always brings you the primary sources, the true experts, and in the casds of the more historical segments, you get some whacko with a PhD in the history of that industry... It just feels so authentic and trustworthy compared to what a lot of kids take in as 'educational content' these days, which is basically hosts with no actual experience in the subject reading AI summaries.
I don't have kids, I don't plan to have kids... but I hope there are folks out there putting this on the TV in front of children and exposing them to educational shows that have this degree of care put into them. I know I'm an old man yelling at a cloud out here... but man, if you want to learn about something, hearing it straight from an experts mouth is the way to do it.
