answer:If the power grid shuts down, information will be the least of our problems. Regardless, digital information is stored on supports that are perfectly usable without the power grid itself, you just need a generator to power a computer for a while, and considering we have stuff like the Raspberry Pi even a dynamo could be enough. The problem with the cloud is not the digitalization but rather the delocalization of the drives, that in such an event would make the recovery impossible. Your files could be on a server in New Zealand for all you know, there is no way to tell where they are stored and there might be issues retrieving them. Then again, as a CS student, i can safely say that if you’re using a cloud drive as your ONLY storage, excluding even your own computers’ hard drives, you’re stark raving mad and losing that information is probably well deserved.
