Yeah nah, I'm sure every generation will cop flack for something, it's just that since WW2, and the cold war, problems like plastic, lead paint etc let alone the environment weren't really on the agenda. People just didn't have a list of big bad world problems besides war.

On one hand I agree that technology is changing at a rapid pace, and ageism is a thing, especially more so now with climate change, but I think the issue is how quickly can the "wall of education" be broken down so that a critical mass of the human population can be enabled to learn how to calculate complex integrals, produce a computer software and program, to make a pipe bomb lol, or fix their car etc, you get my point.

Information freedom is becoming a big deal for people these days but at the same time individuals are no longer expected to be so rigidly self reliant. First it was paper, then books in libraries, nowadays we have the internet. YouTube, torrents and search engines definitely help a lot, but I haven't seen a top ten problems for humanity video on YouTube yet lol. We're almost coming full circle, however, I still think we should pay homage to the idea that being self reliant and learning how to do something for yourself is essentially a good thing, not necessarily only valuable to prevent loss of information but for further collaboration opportunities. It's not necessarily Nazism to argue that if every person's mind was a library, idiocracy and risk of displacement would become less likely to occur on every level. Think of Hal from A Space Odyssey

Your mechanic can fix his own car the same way your locksmith can unlock his own van, and your tech support guy will probably learn to fix his own computer. If you can do all of those things, even if you don't become a valuable person in society, at least you'll be better at taking care of yourself and less likely to be a burden to your group.

In saying that, if I was an old 60-70yr old man, I would consider re-educating myself in a field not so hot for the younglings, you know, the usual work like the trades, engineering, computing, and big data are big money for many young people these days, so it makes sense, if you're older to get into something less physical like painting, gardening, landscaping, digger operator, software UI development, accounting, systems engineering, matchmaking, etc, something that is either boring or niche enough that many avoid it while simultaneously needing it. Remember boredom is the weakness of the younglings lol
