Our reality is a simulation designed to test whether it would be better or worse to change the social conventions so that shaking hands with someone no longer requires doing a full thumb war with them (which is how they do it in the real world, and you can’t do a half-assed one just to get it out of the way, both of you have to be really trying your best). They’re thinking of getting rid of that to save time but they’re doing this simulation to see if there would be unexpected downsides. It’s vitally important from our perspective that not too many people know about this because then it would corrupt the data and they’ll shut us down early. I’m posting about it here because it’s not a big deal if some people know, but I’m not sure exactly where the line is so obviously use your best judgement when talking about this.
