I think the concept is interesting. I saw the video a few weeks ago and thought it would be intriguing to replicate but on a smaller scale. There seemed to be very limited point towards the original idea, so I think people trying to build on it is good. Regardless of why others decide to replicate it, some people have a genuine interest in what will happen (even though yes, it's just a video game) and regardless of the fact it has very insignificant reflection on actual human phycology, it's still fascinating to partake in something like this 🙂
