Re: Could we manage without technology?
We may manage, but mainly humanity will digress to a point prior to Thomas Edison or to times of native savagery. Many will die of course, as life support will fail forevermore and hunting will become a new pastime for humanity as our violent shows will then have to be replaced with live violent entertainment.
Of course when the electricity first disappears there will be lots of people who will riot and cry out about the end of the world. Anarchy will arise and all will be total chaos.
As the likelihood of all electricity disappearing is pure science fiction, humanity has nothing to worry about.
