For me it is a nice counterweight to the idyllic future Silicon Valley paints, its nice and understated, compared to the bombast of TechCrunch articles hawking the next greatest start-up that is going to "Change the world". It's nice to have balance in my life.
Whenever I hear an entrepreneur (and the tech media) breathlessly excited about how so-and-so technology will "change the world", I try to figure out whether they mean "Star Trek" change or "Black Mirror" change.
Most often - neither. Because they're not so evil that they'd like to bring in a "Black Mirror change", but on the other hand if they understood Star Trek, they wouldn't be doing what they're doing (or, at least, "calling it changing the world"). Indeed, most often "changing the world" means "changing the contents of my wallet".
