I don't believe humanity will significantly regress but will instead eventually achieve true freedom, anarchy. The black markets, the agorist markets, are steadily infiltrating the government monopolies and replacing them. It is only a matter of time until government goes kaput. There are simply going to be too many people with too much free flow of information for them to maintain their protection rackets much longer. Black market currencies like bitcoin, for example, are steadily eroding the state's control of all human action as are many other agorist efforts.
Obviously, governments are becoming ever more tyrannical, but this isn't the only measure of progress and regression. They will collapse themselves and humanity will continue moving forward, with setbacks along the way of course.
