Good read, thanks. This all boils down to simplicity as being the 
ultimate sophistication. People are lazy (in the good sense) and don't 
want to be reinventing the wheel. They would pay more for a 
device/software that solves more of their problems and is easier to use 
(vide MacOS vs Windows with their ecosystems), so that they can finish 
earlier and get on with their lives.

I may be enjoying compiling packages on FreeBSD and manually configuring 
the network but I can hardly expect someone from my team to do the same. 
Docker simplifies their life and I can't blame them for using it. I can 
only wish there was a similar tool to achieve the same with bhyve/jail.
