I see a LOT of young people here interested in motorcycles, and quite a few interested in old ones. When I go to a show/swap-meet that features old bikes, there are a lot of old gray-headed geezers like me, but there are also a lot of young folks of all ages.
In the USA, from about 1920 on once the Model T took hold, motorcycles have NEVER been about transport except for a few weirdos like me; they've always been recreational toys and lifestyle statements. I don't see that changing much, and prices for A65s or Norton Commandos have more than doubled in the last 15 years; they'd have to fall a long way to get even to 2010 levels.
If you focus too much on the news, that "dystopian future" looks likely. But if you're like me and don't pay much attention to it, and take it for what it's worth (which is just propaganda for the Ruling Class), and spend more time talking to neighbors, friends, etc, you'll find (at least here) an awful lot of people who aren't going to let things get that far out of hand, like you see in the nightmare cities created by racism, bigotry, unlimited immigration, family breakdown, and other Progressive policies. It's not all like that, and it'll go as far as we let it go ... !
Be all that as it may, there'll be bikes enough to see OUR time out. After that, people will have to deal with their own weather without me putting my gab in ....
