The week's question
In March 2025, in the thread "Re: OT, out", Umm asked the members: "Do you think it is because America is made up of magical soil that makes businesses based in America magically profitable?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

How do you know when your calculator works or adding machine or anything else?
When it comes to calculating I trust AI; I gave it the best data available. Math is math not opinion.


When I use a calculator or a spreadsheet to do math I can check the output to verify it is right.
The _interpretation_ of the calculations and the data fed into them is up to me.


And AIs are not Artificial Intelligences, they are Large Language Models. Sure, they probably do the math right, but you can't just point it to a bunch of raw data and tell it "Fetch".


If you want to see some hilarity, go to youtube and watch some of the videos of a flat earther arguing with ChatGPT about the shape of the earth.
