That's what I don't get here that worries me. It feels either like a ticking time-bomb to deprecation, and/or a privacy nightmare if they're somehow selling data they mine from their users.
It'd be neat if the software was opensource and you could point this device at your own LLM, then at least you'd have some assurance it won't be e-waste if the company shuts down.
But I don't see a world where you can feasibly support the required infra of providing LLMs for your users with only hardware sales as a revenue stream. Their website specifically calls out that there is no subscription fee, so either they'll introduce one later or something else will need to be the other source of revenue.
