I googled "What was good about 2020?" expecting the browser to go dark and be replaced by the words ARE YOU KIDDING ME? but one of the first results was "Wonder Chicken Discovered."
Turns out Australian archaeologists unearthed a 66 million-year-old chicken, and dubbed it the "Wonder Chicken" because it looked like a duck on its back half. Front part was all chicken, though. This provided new information for scientists, so we can learn how partial chickens became entirely chicken.
So what, you may sigh. With all that happened, we're supposed to dance a merry gavotte because some diggers found a proto-clucker with a duck caboose?
Well, here's another positive development. Private space programs sent up rockets that landed like the spaceships in 1950s movies, on a column of fire with legs extended. OK, a few blew up. (Hey, you can't make an omelet without getting yolk and shell fragments all over the kitchen walls.) But we have a madman billionaire who wants to go to Mars, and my money's on him.
JFK may have said we choose to go to the moon not because it is easy, but because it is hard. Elon Musk says we will go to Mars not because it's easy, but because it's cool.
And it is! This is what humans do. We put little robots on other planets to drive around, or land them on asteroids where they pick up rocks and take them back to Earth, and we do it for the same reason we dig in Australia looking for ancient chickens. We are relentlessly curious.
