A lot of people who say this kind of thing have, frankly, a very shallow view of what homework is. A lot of homework can be easily done by AI, or by a calculator, or by Wikipedia, or by looking up the textbook. That doesn't invalidate it as homework at all. We're trying to scaffold skills in your brain. It also didn't invalidate it as assessment in the past, because (eg) small kids don't have calculators, and (eg) kids who learn to look up the textbook are learning multiple skills in addition to the knowledge they're looking up. But things have changed now.
