It's practically here though. With Alexa and Google voice command boxes which are easily set up in your home and connected to your phone or internet, it's practically the same thing.

Also, there was an article a few months back (if I can find it again, I'll reply here with a link) that basically verified that the people China have been spied on for years already with small cameras and listening devices installed in their TVs. Who says that they haven't been doing that to our TVs or other gadgets besides our phones? Anyone who isn't smart buys new age t-stats, washing machines, alarm systems, doorbells, etc. that connect to the internet, but forget or ignore that microtechnology exists. If you don't open up the product entirely you may never know whether small microphones or cameras exist within. Regardless, it's easy for hackers to go into such systems and steal information or gain access/control to such appliances. It may seem dumb or paranoid, but it's the first step to controlling your life. With the amount of such products coming onto the market, that is yet to come.
