The end of your message is so much worse than whatever you imagine young people to be doing. "Good luck", really? Condescending much?
Also you're pretty damn wrong about those young people: they're way more active than you think. But you seem to be quite aware that it's going to be terrible in a few decades yet you're happy simply making small changes and seeing "what happens over the course of many decades". Wilful ignorance much?
The cognitive dissonance in your words is strong, and instead of actually looking inwards you're content thinking that the people who are barely out of their teenage years should bear the blame for being born with a smartphone in their pockets (thanks to which generations again?).
I sure am glad that they aren't learning from your attitude as they work towards being in a position to be directors or politicians or CEOs. You or I might not be there to see the worst of it, but I'd take their attitude over yours any day of the week.
edit to the person pointing out the word "decades": I replied to a message on their own terms. I'm fully aware that things are unravelling right now, but I don't even need to shift the point and start another debate in order to prove them logically wrong.
