I can't tell you what I was thinking then, but now I wouldn't say that was the main reason to "tinkerbelize." I mentioned in the next sentence that there will be a lot of physical work to supervise.

I do think that it is easy to underestimate the cost of simulating a vivid shared natural-appearing reality, and that people will be uncomfortable with the very fact that it isn't real.
