I like the innovation. But I refuse to connect my private seed to anything that touches the internet. Or use a device that has the capability of connecting to the internet

My thoughts exactly
I must be fair here, the risk is way lower than you think.
Buses like USB and NFC are pretty simple under the hood and aren’t the cause of attacks.
Usually, it is the OS’ fault for trusting any device what it is (like a keyboard), or trying to go too fast, using things like DMA which if misconfigured can be exploited.
On microcontrollers it is pretty easy to audit the entire stack.
It is impossible to execute an attack via USB/NFC/whatever alone and requires either a high attack surface by the firmware developer or a backdoor.
