It seems pretty obvious to me that if we turn the whole internet into Third Life, it will quickly devolve into groups of people standing around and shouting at each other. And that test drive? Even assuming a few people do actually want to do that, 30 seconds in, the car will be full of monkeys and the wheels will turn into cake because the sim was coded by humans on a budget and some 12-year old was bored.

As ever, the grand vision totally ignores the realities of human nature.
