and by that point, privacy will be simply an abstract idea and not something that exists anymore.
Privacy doesn't actually exist anymore for the majority of the population. Only an illusion. You only have to look at some of the revelations surrounding Snowden, the NSA, Cambridge Analytica, Five/Nine/Fourteen Eyes, etc. And these are only the things we know about, that have been leaked. You can guarantee there is far, far worse still hidden from the public. You can tweak your Facebook settings to hide certain content from other people and tell Google to stop tracking your location, it makes no difference. We know these companies collect all your data regardless of what you ask them to do. Every website you visit, every email you send, every piece of data you sync to the cloud, everywhere you go, everyone you meet, everything you say. They can turn on your cameras, your microphones, your GPS trackers.
The scariest part of it all is that
people don't care. Not only do they not care that they are being monitored, they are usually more than happy to help out and pay for the privilege by buying technology such as smart TVs and Amazon Echoes which have been proven to be monitoring you. People are quite literally paying to bug their own house.
Privacy is no longer a right for most people. It is an inconvenience. They are happy to have Amazon monitor their conversations if it means they don't have to (God forbid!) press a single button to skip to the next song. They are happy to have Facebook track their location if it means they can share pictures of their Starbucks coffee. They are happy to have the bank keep a track of everything they buy if it means they can just tap a card and not think twice about it.
We are ever more living in a surveillance state. Surveillance breeds compliance. Meek, fearful, unthinking compliance. You'll never step out of line if you know you are constantly being watched. Anything that can break that cycle - Tor, end-to-end encryption, PGP, bitcoin - is only going to become more important as time goes on.
