Back in the C19th they didn't care about clean water and drainage. In fact Joseph Bazellgette was lampooned for suggesting that London needed such things.

Amazing what rampant Cholera and Typhus can do to change attitudes.

We haven't had the data equivalent of those diseases but we will do and probably soon. At that point we will learn some very harsh lessons.

I think those lessons will come when the new memory technology that allows you to have an affordable 16TB rather than an expensive 16GB laptop comes into play. At that point computers will be so powerful that every one becomes a supercomputer. Black hats with their own personal supercomputers. God help us all.
