Ufff happy you posted this, it needs an adjustment because it's not inherently true but is a common (potential) fallacy.

You should never look at your electronics as a persistent backup.

Especially if you have a Coldcard for ex, as a lot of complaints of coming back to a stored device & have it be completely bricked.

It's the #1 issue / complaint with their devices.

But I would treat all HWWs like this & make sure you have backups of your seed phrase(s).
