Do you worry about our hobby dying?

[ATP]

I wouldn't have any worry at all about the next thirty or forty years at least. There are a lot of folks in their twenties and thirties who collect...and finally now have the expendable income. They grew up collecting in the eighties and nineties...likely got out of the hobby for a little while around high school and college age, then come back to it when life settles down a little more.

A lot of people I talk to are in their thirties and they assume they must be part of the younger group, but that group is actually quite large.

Collectors typically collect until life no longer allows them to, so there are quite a few good decades left from that group alone. There are also a lot of people in their teens who collect modern, and occasionally drift to vintage. Beyond fifty years or so who know what people will be doing, but I don't think most of us here will have to worry about it dying out during our lifetime.
