One of my least favourite feature of our AI era is that I can't even trust people to do basic math anymore. It used to be that a graph like that would mean someone had a (probably broken) metric that they put in an excel sheet and got a lineplot out of it. The metric might be broken but at least additions and subtractions etc were correct.

Now I don't even know! Colleagues send me graphs they made with Copilot and then we discover that the LLM did mental arithmetic or whatever to produce the results and they are wrong. Computers used to be able to do math !
