Okay so for example:
Playing video games: we got AI shenanigans and cost of computers rising (not just gaming computers but electronics overall), its possible that in 2030, nobody could afford a computer so the one you got could be the last one you ever have (lets hope not, but like its not impossible)
…
I do wonder tho: What hobby is actually shielded from turbulent times.
Model trains is the only one I can think of. Unlike my other hobbies of electronics and cars, vintage model trains have already gone up and mostly come back down, and so are affordable at any train show. Of course there are pieces that are in the thousands, but there are a lot of very cheap pieces.
The retro game scene is somewhat similar, eh. But we’re in the era where people think old means valuable. A Mario/Duck Hunt is not worth 20 dollars. But people pay it, so the floor for common stuff is too high now. You need to go for weird games that slipped through the cracks.
