This whole thread is pretty much just FUD.
Any relevant change to protocols will be implemented as a firmware update to Trezor devices.
Trezors are not 'subject to failure' as far as I know.
Paper is hardly more secure or long-lasting.
Well I am no expert. I was just looking at what Andreas said.
The issue he's talking about is that it gets harder to change a protocol when it starts to become embedded.
It's not that the protocol changes can't be released as an upgrade, it's more that there are many devices that will never get upgraded for various reasons. Think about stuff like home routers, for example, that never get an upgrade.
If the network stops completely, people would either learn how to do it, pay someone to do it, or buy another router
Bitcoin involves their money, so I'd think the incentive is there to get the upgrade particularly if they can no longer access their money. Upgrades that just add features will likely not get done.
