I have an old desktop, no camera or mic. We don’t have much in the way of “smart” devices.
Good, what you have might be okay unless they put cameras and/or speakers in/as part of behind the screen and/or cooling vents areas.
They call all that BS “smart” so all the DUMB people buy it, use it, etc. How gullible and absolutely stupid ALOT of people are. Same thing with Alexa, echo, siri, supposed “home security”, etc., into infinity.
