> They should feel more comfortable than an equivalent system built by a company that is looking to profit off of your data - and additionally, you can give the guest stronger guarantees that when you say that the system is "off", it actually is.
They won't, because they'll be concerned the person that implemented it is a creeper. When regular people think "cameras installed in the room," they think this: https://www.bustle.com/p/airbnb-host-was-caught-with-a-hidde...
Distrust of a person is more more immediate in visceral. Distrust of a company is more distant and esoteric. The former usually trumps the latter.
Your vulnerability isn't a targeted attack: you are not valuable enough to be worth the effort to figure out your system. As an attacker on your system I'd have to figure out how to break in, and then how to use the hardware you have. You are more valuable as part of a botnet - attacks that already exist. (if you are a politician then maybe, but that person is also vulnerable to a targeted attack on their amazon system - probably more so because the target is easier to figure out).
That is they will target everybody because they know in a few years that will include somebody who they currently think is a nobody.
Of course as AI gets better and cheaper they may eventually listen to everything to see what who can be targeted automatically for what.
Just working for a company that an agency is surveilling is enough to make you worth targeting.
As a random example: let's say that I want to kill someone who lives in your neighborhood. I could analyze your conversations, comings and goings to figure out when and how to kill that person, and blame it on you. I could on a continual basis run numbers on everyone emitting data in your neighborhood, until someone had arrived at a point where their friends would testify against them on the basis of conversations with the potential patsy, that patsy had no alibi, and tailor the murder on the basis of the means that the patsy had available to them at the time.
I could also just be trying to figure out if you were a homosexual, or muslim.
