if your hardware stops working, you're a dead man.
No, you are not.
You probably don't know that you can import your seed from a hardware wallet to an Electrum wallet. To easily understand it, you can easily connect your wallet from that hardware even if it's broken with the use of Electrum wallet.
I guess the OP says that if you don't have the backup of the wallet then you are dead, well that's with every wallet out in the market as well, if you are using the software wallet then also you are prone to attacks and your funds can easily be stolen by a hacker or the person having physical access to your wallet as compared to a hardware wallet where funds are more secure than a software wallet and always is password protected by default.
Also I didn't knew about the importing of key from a broken hardware wallet to electrum wallet, should it be from a backup or we can also extract the key from the broken hardware wallet??
