Does it? If you saw a bike racer riding an old steel commuter bike with mudguards and pannier rack, because lots of people ride those, wouldn't that be weird? Bike racers ride lightweight carbon fibre bikes and they do so because other bike racers ride them and they could not be competitive with something much heavier and less aerodynamic. They use every advantage they can get.
If there was a programming language which was unusually good for rapid data crunching, over several years of AoC wouldn't you expect it to become the dominant language on the leaderboard?
