Imagine a world with wide spread trezor adoption.
I'd probably be in the minority when I say this, but if that becomes true I would get rid of my trezor. Privacy and such stuff.
Reality would be, I'd keep one for regular stuff, for convenience, but for everything else I don't want the world to know, it will be offline / off-the-grid.
What you described looks like a database of everything you do attached to a device. Whoever owns the company behind these devices would be rich with data (which they can sell.)
