Software for maintenance devices shouldn't be written so it forces people to use a cloud service unless they can guarantee that will always work. There's about 1000 points of failure in that.
Actually, I'm pretty sure DVDs and music CDs and games only exist because that was their only option. If you look at what the law is and what they're trying to do, you don't own the rights to the game you buy.
If they could forcefully take it back from you and disable the in game radio because their license expired, they would. And they do, when they can. Same with movies you "buy" instead of renting for money. They can and do just change their licensing and remove it from your account.
Game launchers also do this. If you get banned in 1 game, they can just delete your entire account and all linked services because you're not really buying the game.
You're barely even buying a license to use it. You basically have zero rights other than where technology has limited them.
Anyway, that aside, software shouldn't be your only concern. It has all of the visibility right now, but tech hardware should also be up there. Physical life of tech is currently terrible. An unopened, factory sealed electronic left in a store will still die after like 5 to 10 years. Nobody wants to or can feasibly repair it so it's just e-waste. Analog equipment exists for some things with higher tech solutions adding functionality and reducing power in some cases, but I'm curious to see more data about how these truly compare.
I came across this while looking at how to backup data for a long time. I was also curious about the case of analog devices in space. It's been hard to find a lot of info about it.
