People can use AI to gain insight and ideas on certain topics which they don’t know anything about but it also has its own risks. The more people interact with AI, the more thinking AI will be doing for people. As a result, people will lose their ability to think. In a few years, there will be many people who will be asking AI’s opinion whenever they decide to do something. “Hey I am going to go get a beer from the fridge, is this a good idea? What’s the possibility of me catching a lightning bolt on the way?” You might laugh at this at the moment but it is coming. We are probably one of last generations who do the thinking themselves. Soon AI will takeover that field.
This is already happening today - and what's worst of all is that I see a lot of children who communicate with AI instead of real friends, and we've all seen that AI can sometimes (and has already done so) influence young people to do something very bad, even to take their own lives. Even those who
"invented" AI are starting to seem concerned, because the direction we are heading is definitely wrong.
OP, people still plagiarize because it's easier for them, they find an article and copy it to a forum, which seems quick and easy to them. Besides, it's easier for people to detect AI content than plagiarism these days.
