Maybe, but I suspect you're smart and have the intuition to "just know" if something went very wrong. For example, if you multiply 5 by some other integer and the result ends with a 2, you'd just feel it in your gut, no? This is not true for everyone!

It's not uncommon to have folks with reasonable math skills ending up behind a cash register and insisting they're right when such errors occur and I see a high likelihood of this happening with relying on "AI" too. Domain knowledge and good intuition will continue to be valuable.
