It’s neat to think about what units an alien civilization would come up with independently. Like the Plank Distance is fundamental to physics, so they’d probably have something for that.
Degrees Celsius is based on freezing and boiling point of water, so if they came up with a base 10 numbering system and water is key to their biology, then they’d probably come up with that.
A calorie is the energy needed to increase the temperature of 1L of water by 1C. A liter is a volume of a cube 0.1m on each side. The meter was originally ten-millionth of the distance between the equator and north pole (and subsequent redefinitions are based on that original measurement). They wouldn’t come up with the meter, and they wouldn’t come up with liters or calories, either.





Just had a conversation about this. I’ll copypasta what I said there.

tl;dr: they’re all in on AI (their own model, FastGPT, which is terrible), they make some very questionable business decisions with limited funds, and have a poor understanding of what Personally Identifiable Information (PII) actually is.
I could compromise on some of these things, but if I’m going to pay for their service as a Google alternative, I need to compromise less than I do with Google already.
