Is AI becoming redundant to society?

I did a speech and debate tournament at an Ivy and it was strange how many people mentioned AI. It felt like nearly half of the conversations involved AI in some way. This is great, but it also seems like AI is making things redundant that people enjoyed about debating and having discussions. I heard a lot of people mention AI's the perfect thing to find information and also makes arguments completely redundant because AI can find the same information much quicker and with reasoning that is much better than what people can come up with. It also introduced something called "AI arguments" in which people will say that you can't attack an argument an AI makes because (1) you are attacking a person who isn't there and (2) it is impossible for a human to have a better argument than an AI, so your argument is therefore null and void and the AI has won. They said that it should be put in the rules that you can't attack an AI's argument, although it isn't yet. Someone also said that they would not bother to learn how to write because an AI could do it better and faster. I don't know what to think about this. Do I think that AI is a positive part for society? Absolutely. Do I think this is a problem? Also yes.
