Very interesting watch. Shows very clearly how different prisoner’s dilemma strategies work and what traits make a successful one.

      So conventional models describe electricity as flowing through the wires at the speed of light, (this model is extremely useful but doesn’t accurately describe the underlying mechanism) so it makes sense that it would take 16 years in the aphla centauri example (8 years there and 8 years back) for the information that the switch is closed to reach the lightbulb, and that is what happens irl. The full voltage does take that much time to travel the distance BUT because electricity and moving electrons is more complicated and is carried by the electric fields, some of that electric field reaches across the gap and puts a tiny voltage across the lightbulb, which in his example immediately turns on to full brightness at any voltage difference.

          Oh apologies with a missed detail. The battery+switch and the lightbulb are 1 meter apart and are connected by a wire that is 1 lightyear long.

          Assuming that electricity is only carried inside the wire (like our conventional understanding and models expect), yes it does break the speed of light but electricity doesn’t actually travel inside the wire but in the electric field around the wire, which gives the wire near the battery to affect the wire near the light and create a tiny voltage difference, thereby nearly instantly lighting the lightbulb that reaches max brightness on any voltage differential.
