On another topic, someone recently posted this youtube video of a Norwegian engineer explaining her views on tech worker ethics, how we've got here and maybe a way to fix it or atleast improve on the current situation. I'd recommend showing it to your commute buddies.

It really resonated with my thoughts, how I've viewed the tech world and my (tiny) part in it.
