So I realized yesterday that you can match your GKC game with a local version. That means even if the servers go down a GKC could potentially be used with a friend's Switch 2 to download the game. Your friend just needs to have that GKC game on their harddrive. Regular Switch 1 carts are supposed to only last 20 years. But then again, VHS was supposed to only last 25 years. And early DS carts should have died by now too but a majority of them still work.
Anyway, even after the servers go down and all proper physical cards die to memory rot you might be able to still activate a GKC if you can find someone with a working Switch 2 that already has said game downloaded.
I'll still avoid GKC and only buy one every three or four years though.
