It does seem kind of odd doesn't it? In an almost surreal sense, too. I can't help but think of 'Soylent Green' and other dystopian horror media. People were at one point scared of the future we're creating right now, and I wonder when it was exactly that people stopped being cautious.
The lesson is that too much of anything isn't good. Every problem we solve will introduce new problems (for example, the Green Revolution stopped billions from going hungry but now we have nitrification of soils). Sometimes we really gotta ask if the problem we're solving is worth the cost.
