That’s correct; dictators rarely understand how the weapons they use work. I doubt there are many politicians who can describe how a nuke works, but they’ll continue to threaten to launch them. This is not a bold or surprising claim, is it? All they need to worry about is that it works ‘often enough, at a cheap price’.
And my point is not that you should use AI for addition. We agree it is the wrong tool (and modern models will just call python). My point is that AI completes tasks in weird ways that are hard to predict; the sweatshop analogy, remember?
Finally: Maths is not magic handwaving, but there are many many ways to perform simple addition. Homework exercise for those at home, find 3 different (equally correct) algorithms to add single digit numbers.
