Have you used, say, Solaris or AIX recently? They have evolved as well. In particular Solaris changed a lot in version 11. AIX has always been different afaik. The problem is not that Linux is no longer "Unix" (Unix is no longer "Unix"). The problem is that people don't like change.

How do you know?

But the food is unevenly distributed. The world population has stopped growing where the food is available and you can expect your kids to survive.

But the population isn't really increasing in the western world where we have all the food we can eat. By your reasoning western populations should be increasing a lot. The number of people will stop increasing when also poor countries have enough food and good health care so that parents are confident that the children they get will reach adulthood.

They DO measure streaming as well, at least here in Sweden. I've got their equipment hooked up to my TV. They snoop on the sound from my media player, game console, etc, and on the sound from the TV to the receiver. This way they know what piece of equipment made what sound when, and by using (I guess) some kind of fingerprint algorithm they can compare it to a database of known shows/movies/whatever, and compile the result.

Seconded. I'm running a similar setup right now for precisely these reasons, although I'm not running FreeNAS virtually, but rather have a dedicated machine for it. Once you get used to ZFS you will not want anything else (possibly with the exception of btrfs once it matures). I'm currently moving away from Linux to PC-BSD (an easy to setup FreeBSD variant) to be able to have a ZFS root file system. Snapshoting and cloning are incredibly useful even on a single-disk machine, and incremental backups are trivial.
