the recent movie 'In Time' with that Timberlake dude is quite reminiscent of what could happen in a bitcoin controlled world. you should see it, it's very good (IMHO) .
Somehow I did see that, think I was staying in a hotel and it was just on. Didn't even know it was Justin Timberlake because I am not hip, but I did like it very much also as a concept, analogous to the money system we have now I thought. Just more efficient.
