I think these are the first steps of a major change ahead of us in the next 10-20 years. Think about the GRID and even vaster broader transport systems and think about how display technology will change in that same timeframe. What if a super thin panel, super high contrast, energy efficient display technology (maybe even advanced OLED) became the norm. What if you could put a 4'x5' 1/8" thick screen on the wall that you could steam art too it... why would you ever buy art at that point.
Think about the work place... why would you go to an office. At some point many of us will just have huge screens at home and work in a virtual office where we can go have a meeting whomever we want... we can see them, hear them, in real time. We do that here at my office sometimes and it's kinda of amazing, but think about where it'll be a decade from now.
Given that, if you're an artist, would you rather sell one painting for $1,000, or lease it out to 100,000 people for a $1/month? I think that's where we're headed and many things as we know them are going to change... and I think that change is happening faster and faster.
I don't want to be like the last guy in the country making buggy whips. I'm sure he made the finest buggy whip ever to be held your hand, but as he looked out his window and saw cars, I wonder what he thought.
