Very interesting watch. Shows very clearly how different prisoner’s dilemma strategies work and what traits make a successful one.
I’d love to know what the downvotes are about. I found this really interesting and wouldn’t mind hearing a counterpoint or two.
If I remember correctly, Veritasium had few misinformation videos.
Not exactly misinfo but definitely based on some slightly less than honest setups.
Like the speed of electricity video. He was technically correct that his hypothetical instant lighting lightbulb would light up when the first tiny bit of current crosses the gap using EM waves, but it didn’t quite account for our general understanding of lightbulbs work and it wasn’t adequately explained that the lightbulb didn’t act like a real lightbulb, unlike the hyperreality of the rest of the setup in the hypothetical experiment.

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.
