It's laziness, plain and simple, it was never about the ease of access to information from the internet. No matter how easy it is to get information from the internet, there will always be people who will plagiarise or use AI to write a post for them. There is no changing that, and it shouldn't be a surprise that the thread you mentioned is still active.
Some just wants to bypass or boycott protocol to get quick results which is not so here. They forget that there is always a price to pay if one must grow up in the forum and achieving this, one must make sure of quality contribution and this is what counts for them but they still will use AI for posting because they do not really know or have idea on what to do, some even use the AI to post out of point and when you read it you will wonder if the person who wrote the statement really read the OP before posting.
