Education does not work that way: it is not any shallow programming of reactions, but enabling in the individual a deep growth.
That depth is absolutely crucial in a society.
And your examples are staggeringly tied with contexts in which superficiality is the crucial factor for not seeing the matter nor the issues around the matter.
Saying thanks to Alexa even when you know she’s not a person is not a sign of (lack of) intelligence. It’s a sign of manners. Don’t pat yourself on the back and say you’re intelligent because you express good manners less often than the next person.
While I think it’s a bit silly that the researcher thought the chat bot was sentient, I don’t think it’s silly that the bot is perceived sufficiently human to be worth of manners if Alexa has been there for almost a decade.
I don’t think we should teach people that bots are explicitly not worth a level of manners even at the cost of a strange life-like sympathy some may develop. It took us hundreds of years to teach people that human slavery was wrong and we should treat actual people with respect - and many are still pretty bad at it. Frankly society needs all the practice it can get.
Society makes a ton of “factual mistakes”. Look at all of religion, most of politics, a huge amount of history books, much of lower-grade science education. It’s all full of “factual mistakes” that, today, probably have higher social costs than someone being nice to a robot.
What would “training” even look like? Mandatory bot-sympathizing “reeducation” classes in elementary school? We couldn’t even teach people vaccines were safe and worth getting during a pandemic, but we’re going to trying to tell people not be be nice to human-like things? I can’t imagine how high the social costs to that will be.
