I’ve thought about this myself during a phase of less that then perfect health. I think a somewhat practical solution is to have all passwords and documentation on how to use them/access the services that require them in a (online) password manager (so it stays current). Then have an USB stick with encrypted login credentials and OTP backup deposited at a notary and hand out the decryption key to a few trustworthy friends and family members.
This way nobody can access your stuff and the notary can make sure to hand out the USB stick only to the one person you specified in your will. The other friends family members are there as backup in case your “special” friend has lost the decryption key in the meantime.

The alternative to an online pw manager would be a local one that you synchronize to your friends and only the notary has the key to unlock the database, which they only hand out according to your will.

I’d love to hear about other solutions though. Maybe there’s a better option.

P.S.: There are tools to have more redundancy on USB sticks and so on, so that bit flips/degradation can be accommodated. Multiple redundant data carriers are an option as well.

a) Release a Steam Deck successor (Steam Deck 2, 3, 4 or whatever)
b) Have the Steam “Box” have the same hardware as the Deck of the same generation, but with a higher TDP (and better cooling), maybe better storage options and a bundled controller
c) Break into a broader customer base by bringing the Deck and the “Box” to other retailers and stores (Amazon would be a huge one, but also big national brick and mortar franchises outside the US)
d) Maybe do some advertising??? Most gamers don’t even know about the existence of the Steam Deck yet
e) Bundle games or Steam gift cards with the console (at least for offline stores)

Any objections?
