There will always be some form (even if informal) of governments.
And I am sure there will be basically the same type of governments before I die. So nothing will change for ME (or you) for all practical purposes.
Nothing will change until the majority believes it can change, guess who's winning?
Then that majority will be the "new" government.
Well that can be debated but its not worth the time sink until the majority can envision governing themselves then at that point we will be evolved enough to give a new method a try.
Until then new forms of governance need to be developed, a trustless one would be a nice change don't you think?
