"So, you're against using genAI agents in education? What's your stance on calculators then? Gotcha here!"
My dude (why is it always a dude? No, don't answer me), your argument has more holes than a colander.
Calculators work. They do exactly what the people who want you to buy/use them claim they do. Not so with genAI chatbots.
Perhaps even more importantly, the existence of calculators does not negate the importance of teaching kids basic arithmetic. That is because what's important is not just the result, but also how you get to this result, and why you want this result in the first place. So even if genAI chatbots were failproof, I would still want students to be able to do the work themselves, because what matters is not so much the outcome as the process.
And, as using a calculator properly requires the ability to have some notion of what the result should look like, so as to reduce the very real possibility of a user error, using genAI assistants requires the ability to look critically at their output in order to fix all the errors (that, again, aren't due to user input so much as to their being error-prone by nature).
