Intellect is the most scarce resource. If I were a pilot, it would be much easier to say "This isn't my fault" on a plane plunging to the ground, than to consider every possible way to navigate a hopeless situation.

Apology: I should have taken the exchange rate into account more rigorously. The drastic 96% recovery from 2020 to 2024 is 38% in USD, based on the average yearly USD/JPY exchange rates. (And if we assume the inflation of this period as 20%, 1.38/1.20=1.15, i.e., 15% recovery.)

Showing the (cr) icon is probably not a good idea because 1: we already need to doubt every image on the web today, and 2: seeing this icon on every image is quite unpleasant. I think right-click/long-tap context menu is better (unobtrusive).
