Today computers like imacs, ipads, mobile phones or tvs(not even talking about Alexa), clocks could spy on you in your house at every single time and give the data back to home at the other side of the globe.
Your pulse could be monitored, your movement could be monitored, who you talk with privately could be monitored, who you sleep with could be monitored.
Once this is possible it is a temptation so great for the US Government(or any other Govertment) and status quo to resist.
It is only a matter of time that Governments react. Of course the other powers of the wold want to do what the US Govertment already does.
Massive surveillance spying using technology created by companies of the same country? Already done by the US.
Protecting sensitive data from outside Governments? Already done by the US.
Restricting companies from working in strategic sectors and forcing them to provide source code? Already done by the US.
