What can be done to improve the firmware upgrade for these devices ...to make it "Idiot Proof" ? What happens when Ledger or any hardware manufacturer goes bankrupt and exploits are found and the developers are not there to plug the holes? (Export seed to Electrum?)
I'd say Ledger is already the most "idiot proof" hardware wallet we have right now, with Trezor coming in at a close second. Instead of working to make updating a bit more easier, they should probably just focus on removing unnecessary bloat on the Ledger Live software because it's slowly but surely getting slower and clunkier as time goes.
