Not only that, but people are relying on third-parties to keep the data available 24/7/365 until the end of time. I can tell you for a fact that if a company goes under, so does your data. I had an SVN repository hosted by a third-party. The company went tits-up and al of that data is now gone. There might be a backup of it somewhere but it's inaccessible to the company's customers. This is really no different that relying on some physical media to store data. Long gone are 7-inch, 5-inch, 3.5 inch floppy disks. Gone are Syquest disks. Gone are magneto-optical disks. Gone are Zip drives. Gone are magnetic tape drives of bunchteen flavors. CD-ROMs are probably still readable... if you can find a drive for them. Compact Flash probably still work. SD cards and Micro SD cards, plenty of those around... if you can remember what was on them because you can't easily label them. Oops, did you roll over one with your desk chair? Sayonara. External hard drives? Oh, did it use some long-dead interface like SCSI? Heh. And the drive is also hopelessly stuck. Not to worry though. Most of that data wasn't important anyway.
No real CS student (aka hacker in the vernacular sense) is ever concerned with A let alone B or C. They are only interested in exploration of technology and how to make it do things that the designers and gatekeepers never intended. Read Steven Levy's book.
Think all of that wind and solar was free? And while we're on the subject, the Salt River Project in Arizona boasts that they are a non-profit company which means that any "profit" doesn't really get returned to the customer but rather to upper management.
Only the UN would expect first-world countries to slit their own throats because a bunch of third-world countries did. Sometimes I wish that line from Heavy Metal were true "The UN? It's been turned into low-rent housing."
