On the other hand, Arthropods in 500m years never managed to create 4chan

Dinosaur in their 40m years span didn't get a radio wave out

Mammal in 200m years only managed to get some primate out, 100m years ago, any extinction event in that time frame, and Adios 4chan, Telescope, and bipedal walk

Not only the step from life to multi-cellular life took 4 billions years (1/4 of the universe life). But even after that the progression to intelligence life was long: In all the species around in the past 500m years, intelligence is a fluke.. we're still waiting for its 2nd coming. And Dolphins are more dumb than they look
