As far as contact tracing in the US goes, I'm not that optimistic. Several friends who otherwise seem like intelligent people have started really pushing the narrative that Dr. Fauci and other medical professionals are "puppets of the deep state," with Bill Gates as their leader. They seem to believe that a "mandatory" Covid-19 vaccine is about to be forced upon everyone. So, they keep encouraging people to "not cooperate with the government," because, "the pandemic is just a ploy by the deep state to gain more control over the sheeple." Friends who claim to know that they had Covid-19 last month have told me they purposely didn't get tested, because they didn't want to end up on a "government list." It's depressing to think many Americans are already planning to not cooperate with any future government efforts to do contact tracing, because they believe it's a big conspiracy. :(
This kind of stuff frustrates me a little, but it also makes me laugh.
I won't speak for America, but in the UK, if you have a house, pay rent or a mortgage, have a bank account, have your salary paid into that bank account automatically at the end of the month, pay taxes, drive a car registered to you at your home address, have ever visited a doctor and have a smartphone that is frequently connected to the internet with loads of personal information on it (email, social media etc) they've already "got you". That covers pretty much all of the population between the ages of 18 and 65.
But no, the real danger is the virus and the contact tracing. What do these people think will happen to them if they end up on a government list? They sound like they should wear tin foil hats and live in bunkers in rural Montana.
There's a guy whose Instagram page I have saved as a bookmark who lives in America. I look at it roughly once a week for fitness related things. He's obviously intelligent and well respected in his field, knows his stuff, nice guy. In a lot of his recent posts, he refers to the coronavirus as the "control us" virus and talks about the government etc. It's got to the point where I've stopped following/checking his page because he's, well, rapidly going nuts.
I suppose that's no different from an intelligent, successful, highly qualified person being terrible with money.
