Good as this is, it's missing the parts which lie outside browsers and it doesn't have much regarding mobile devices. In a matter of decades or shorter, I expect the following to happen as well: * Governments will give themselves new, expanded legal rights for mass-surveillance on their citizens through their electronic devices. * AIs will be plugged to surveillance data-streams to search for "criminal behavior," whatever that be for each country. * As part of the above, a signal-processing mechanism similar to the Chinese social score, but way more sophisticated and comprehensive, will be implemented, by almost every nation with the resources to do so. One nation, China, already started. In the decades to come, other major nations will lean on threat of XYZ to follow suit. (In case you need some examples of XYZ: ordinary terrorism, bioterrorism, avoidance of laws limiting AI, child pornography, access by children to pornography, minor solicitation, parent abuse, sexual harassment of nature X, lax morals regarding Y, information warfare by foreign powers). Even if those things seem unimaginable to us now, it is a slow slope to roll down through a year at a time. Public perception will gradually change enough to tolerate the privacy invasions. And who knows, for certain category of threats, it may be that the general public of the time enthusiastically supports the surveillance. (For example, I would love to see a study where people with children are asked if they believe that the government should have access to the telephones of people who are statistically likely to engage in CP, like men who are single and under a certain age, in order to prevent CP).
