> Right, so if they had the same level of police brutality you would have 60 deaths in the history of American police, or about 1 killing per year
Only if problems scale exactly linearly and there are no side effect emergent behaviors you have to account for. Otherwise when a big tech company goes from 1M to 10M users, they just need 10x as many servers, right? Problem solved.
Nope, in real life each order of magnitude has required serious, difficult engineering to overcome the challenges, you should read up on how companies like Amazon/Facebook have scaled with users. I'll give you a hint though - they didn't just draw a line and extrapolate how many servers they would need for each year.
Otherwise you could just say: "Oh, New Hampshire has a homocide rate of 1 per 100,000. New Hampshire has a population of 1 million, therefore that's 10 deaths per million, therefore by simple extrapolation, the USA should only have 3000 homocides per year!"
