Is it really wasted human effort?

Si Lumb once said something like

“We could be on Mars by now but instead we’re wasting effort stopping people stealing Coldplay records!”

Theres been a lot of focus on VR recently and I found Philip Rosedale’s Ted talk interesting in relation to si’s thoughts above, especially since Si is a fan of VR.

ROSEDALE: Why build a virtual world at all? For me, I know that when the Internet came around and I was doing computer programming and generally trying to run my own little company and figure out what to do with the Internet and with computers, I was just immediately struck by how the ultimate thing that you would really want to do with the Internet and with computers would be to use the Internet and connected computers to simulate a world to sort of recreate the laws of physics and how to make things, and do that inside a computer so that we could all get in there and make stuff.

The next frontier may not be space (no Mars or interstellar space trips yet sorry si) but instead the inner space of the virtual reality or rather a space we create and imagine for ourselves and others. Can be equally interesting?
