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.
Conlanging. No less than JRR Tolkien himself noted how wallet-friendly the hobby can be. All you need is stuff you certainly already have, namely stuff to write with. It’s such a niche hobby that there aren’t many commercial tools for it, and any programs like lexicon makers and word generators are usually thrown together by members of the community and offered as is for free.
Also the broader hobby of conworlding, but since that’s basically worldbuilding for its own sake there are a lot of commercial tools meant for dungeonmasters and fiction writers that also work here. Many of these tools require an account (lookin’ at you, WorldAnvil).
