Is there really any point to using a hardware wallet if you aren't using it air gapped?

I mean, basically the whole point of the device is to generate and keep seed phrases offline.

I find it weird when people directly connect their hardware wallets via USB or whatever...

I know that it's a thing with a secure chip supposedly keeping it safe, but that seems to me like a unnecessary point of trust, as well as the connection via USB or even BT to a internet connected computer.

Am I missing something?
