Let's agree to disagree even for that specific Big Mac. I think the likelihood of contamination/ food fraud, concealed scandals, etc is higher in China and NK. Simply knowing it prevents me from similarly valuing the Big Mac. In addition, I often enjoy freely joking about the stupidity of local politicians while eating... and could bring up the building standards, codes, AC, open restrooms, reliability of power grid, etc that won't match US standards and impact my experience as a customer. Anecdotal example 1: In July 2014, Shanghai Husi, a Chinese subsidiary of a US-owned food supplier was caught producing substandard meat products. McDonald's was one of its biggest fast-food clients and had been sourcing from the supplier for more than two decades. After cutting ties with Shanghai Husi, McDonald's China and its branches in Hong Kong and Japan were forced to pull many products from the menu due to a severe shortage of meat and vegetable supplies. Just 1 occurrence of them getting caught, imo more likely to occur in countries with widespread corruption and directly impacting the burger consumption experience/consumer peace of mind. Anecdotal example 2: when I eat I like to connect to wifi and freely browse YouTube
imo PPP is misleading. 1 public toilet in the US is nothing like 1 public toilet elsewhere. 1 housing unit in the US is nothing like 1 housing unit in China. Nominal GDPs in USD fluctuate in value because they are real. Countries in EU, Russia or China are suddenly relatively less wealthy after adverse currency move.
Out of all the ways to replicate a game of life inside a game of life, there has to exist a "most efficient" one for a given size and speed. Something maybe akin to Carnot efficiency. I wonder if aspects of the maximum ratio of scale for space and speed apply to all "simulation inside simulation". And does it say something about our reality? Maybe Planck length is the smallest unit of length and lightspeed is the maximum speed irl and that tells us about what we can simulate and could be simulated from lol
