I agree, but again i go back to, "but how else can it work"?
Of course i don't expect everyone to be knowledgeable on all low level systems. However, to the point of your 85 year old grandma, she is a tiny demographic in a much larger, much more reasonably informed demographic who also completely ignore the implications.
Name a demographic that isn't wildly ignorant of things that are reasonable to know?
But again, i repeatedly fallback to "But who else can do this?". This is why i'm pro Government, but not until people start pushing for responsibility on this front. It may not be reasonable for your grandma to be responsible for Google Data stuff, but she _(and the rest of us)_ have sat around for dozens of years watching authority figures have little to no accountability or oversight.
The issue isn't about Google. The issue is about us, and our inability to build a government and authority system that is in-line with our views. We hand our power over with no thought or oversight and then we're shocked when it all comes back against us. This has nothing to do with Google or CS, imo.
