The alternatives are telephone, e-mail, actual mail, text messages, and other means that are not trying to track, tabulate, and sell you and your personal information to the highest bidder.
Amazingly, people managed to stay in touch for thousands of years before Facebook even existed. Even using computers!
Whether it's the gov or FB or Google, I assume someone is listening in. When it's time for secure communication, I reach for something like Signal. Otherwise, I'll go for whatever is the most convenient (probably FB messenger, or text, rarely email/instagram messenger).
I think the scary part of 1984 was not that the govt spies on its citizens, but that the govt tries to control their thoughts themselves. If thought crime is eliminated via newspeak, the spying is meaningless
Other messaging services: tell someone your username on it (when you ever happen to run into them again, I guess.)
Facebook Messenger: search for their name on Facebook, find the one with the right profile picture, hit "send message."
Facebook is the modern-day White Pages, except for the entire planet.
And that's the part that makes it so hard to "quit Facebook": you're essentially erasing your entry from said White Pages, so people that want to connect to you by name can no longer do so (unless you're famous enough for Google to pull up your Twitter when people search your name; or you know enough about SEO for people to find your personal-brand website/blog when people search your name.)
Nevertheless, services like this already exist. https://about.me, for example. "Vanity website" is the generic term, I think. It's essentially a one-page business card that you can register a domain for.
The difference between these services, and Facebook, is that people sign up for Facebook and fill out their contact details as a necessary step in the process of doing something else they wanted/needed to do. People don't seek out Facebook, they just... end up there. Like your name ends up in the White Pages.
Whereas, these "business-card website" services, you have to explicitly seek out and register with, just for the purpose of having that information out there. Less like the White Pages, more like the Yellow Pages. People that want to be reached out to (i.e. people with "personal brands"—marketers) are willing to go to this effort, but regular people aren't.
It's very unlikely that, if you're looking to connect with someone (who is not the type to create a big public presence for themselves), that they'll have registered with one of these services. Why would they have?
But instead we use a tool,text, that creates very little emotional connection(according to research), addicts people in all sort of ways(intentionally), manipulates them via ads, and creates all sort of negative psychological effects.
And there's no need for VR - high quality video conferecing does the job.
I'm not sure if this is true.
Let's experiment. Let's create a rewarding, addicting environment that will train people not to pay attention, not to develop social skills or empathy(research availble) , and be an easy escape from everything.
What will the result be? people will lack those skills. So for them, Social relationships will become more difficult and less satisfying - so why not use facebook instead ?
