Yeah, but not being able to avoid interfacing with the tech, even if I'm not forced at gunpoint to get it, I still find that unpalatable. If he wasn't the one behind it, I'd still dislike it exactly as much.

I feel the same way about the rise of smart phones and about the sudden popularity of cloud-enabled front door security cameras. Even without participating, there's a you-shaped hole missing from the surveillance state and you're implicitly tracked through that.

As for how external devices are less invasive, they're less invasive because I can disable them, walk away from them, turn them off. Something stuck inside my head and directly interfacing with my brain is way more invasive.
