Yes, green means go!11! Even there’s an old lady that just didn’t finish crossing yet, she just had to do it in the few seconds allowed.
My favorite one is people honking at other drivers for not blocking an intersection because “it’s green!”. I don’t know the term in English but in French it’s a mix of intersection and blocage. Like, if the light is green but there is no space to advance because of gridlock, some apparently like to make it worse by advancing their car in an intersection and sit there while it turns red, and thus blocking the intersection. BuT It WaS GreEn!
When I started a new job in IT around 2009, I learned that AS400 / iSeries / IBM i was a thing, and it’s still doing pretty well with big retail and the insurance business.
In the same vein, the system used by the aviation industry to book flights is also quite ancient but still very much used to this day.
