on the topic of humans being the intergalactic “hold my beer” species: imagine an alien stepping onto a human starship and seeing a space roomba™ with a knife duct taped onto it, just wandering around the ship
it doesn’t have any special intelligence. it’s just a normal space roomba. there are other space roombas on the ship and they don’t have knives. it’s just this one. knife space roomba has full clearance to every room in the ship. occasionally crew members will be talking and then suddenly swear and clutch their ankle. knife space roomba putters off, leaving them to their mild stab wounds.
“what is the point?” asks the alien as another crew member casually steps over the knife-wielding robot. “is it to test your speed and agility?”
“no it doesn’t really go that fast,” replies the captain.
“does it teach you to stay ever-vigilant?”
“I mean I guess so but that’s more of a side effect.”
“does it weed out the weak? does it protect you from invaders? do repeated stabbings let your species heal more quickly in the future?”
“it doesn’t stab very hard, it gets us more than it gets our enemies, and no, but that sounds cool — someone write that down.”
“but then what is its purpose?”
“I don’t know,” the captain says, leaning down to give the space roomba an affectionate pat. “it just seemed cool”
this is the dumbest idea I’ve ever heard but I thought about it for five seconds and realized that if I were, say, a random communications officer onboard this ship and someone taped a knife to a roomba it would take maybe three weeks before even I was inordinately fond of Stabby. I would be proud of Stabby when I met up with my other spacefleet friends for space coffee, I would tell them about the time Stabby got the second mate in the ankle five seconds before the fleet admiral beamed on board and she swore in seven different languages in front of high command.
also by the fourth day Stabby would be in the ship’s log, he’d have little painted-on insignia, people would salute him as he went by, and someone would hook up a twitter account to tweet maniacal laughter and/or a truly terrible knock-knock joke every time he managed to nick someone.
Someone would almost positively attach a tiny camera and live stream Stabby’s adventures to a media account. Bets would be taken on who is next. Bets have to be ordered to stop being taken on who is next because it becomes a problem for multiple reasons. Bets are taken but quietly on who is next.
At some point someone realizes that they haven’t seen Stabby in a while, no one has seen Stabby in over a day. The cam is running but is completely dark. The ship basically stalls out as everyone stops what they are doing to search for their friend. The confused aliens don’t understand why this nonessential and kind of dangerous piece of equipment has got the entire ship in a fit of worry.
After almost two hours, someone thinks to check a little-used storage room in the belly of the ship. As soon as the door is open, Stabby rolls out and jabs their ankle and then whirls off down the hall about its business. Stabby followed someone in without being noticed, and got accidentally shut in. A ship wide announcement chastises everyone about looking before they shut doors.
“But the doors are automatic,” says the newest alien crewmate.
“I know,” says Kzil’tir. They’ve stopped asking. The explanation is always because humans.
