The route that oculus was going wouldn't have made them a 10 billion dollar business anytime soon anyway. it would be a niche of high end PC gaming at least till mid teir PC hardware caught up. It would take lots of time.
I really don't like when someone says that no human needs X amount of dollars. No human needs a car a house or all sorts of things. Most the things I own I don't need as a human. Sorry to rant just a phrase that bugs me.
Wealth is affected by diminishing returns, so the concept isn't inherently wrong.
Going from having no car to having one car makes a huge difference in your life style.
Going from 1 car to 2 makes somewhat of a difference (if you have a family for example)
Going from 2 cars to 20 cars makes less and less of a difference, and taps into another area of influence (in this case, personal satisfaction, assuming you're collecting them).
Also why richer people should be taxed more, proportionally, than poorer ones.
