Sigh. Unfortunately, this has become the de-facto response to intelligent debate and conversation, where the person who says it, was being disingenuous from the start and where they can poke no holes in what was being said.
Its a capitulation and worse instead of saying "I disagree", and walking away in good faith, the person refuses to recognize the other person's humanity, and uses this more like an invective under social coercion and mental compulsion, in other words a false accusation with no proof, as a bully; and you won't find proof because what I said is organic, and the reasoning is sound.
I'm a person, and your absurd reality is not my monkey or circus.
That behavior is at the level of a toddler throwing a tantrum when play-acting fails. Overall, its quite a twisted and evil thing to do when you are not a toddler.
Personally, I don't get the impetus to do this because it doesn't matter that you are wrong in a conversation, or hold a different opinion; the simple saying speaks volumes about the person saying it.
You should be aware that making the choice and taking the action, towards willful blindness of evil acts, is how people become evil people.
They self-violate themselves repeatedly through fallacy (wrath), and other deadly sins (sloth=complacency ...), eventually accepting evil into their hearts themselves, where they no longer resist such choices and repeat such actions until someone stops them.
Denial of existence is an evil thing to do. Its what gaslighters, psychopaths, and worse engage in regularly, and they victimize others through such bullying/coercion. When you do such things, you communicate to everyone "I'm part of that group".
Ultimately, it shows a core weakness of a destructive person, just waiting for the right opportunity and circumstance to harm others, with the convenient willful lie "oh I didn't know", you didn't bother to know; and lip service matters not.
Its sad when people do this, because they don't realize what they are actually communicating by doing it; the accusation is easily proven false, because chain of reasoning isn't good enough, and any middle school student can understand reading comprehension, and quirks of writing competently, enough to see the human reasoning followed consistently.
Something AI doesn't "delve" to do. /s
I would say/warn that you might consider the specific things that action says about you, and where your behavior leads you; hopefully before the next time you think about throwing that around as an invective, but I doubt you will, if your previous pattern of behavior is an indicator.
Objective measure trumps subjective every time a conflict arises, and you seem to have lost yourself in subjective experience, which coupled with AI use leads to dangerous delusion given the right time, and circumstance.
As an important parallel, you might consider why doctor's or psychiatrists ask certain questions like what year is it, who is the president etc, and what it means when your answer doesn't match objective reality in such cases.
The professionals do this to check your mental status, when they suspect dementia, alzheimers, schizophrenia and other cognitive limiting issues may be present.
If you use AI regularly, you might want to think about dialing it back. Its cooking your brain.
If you told those professional's in response, "Nice chat-GPT response", the assumption would be they commit you to a facility or hold for observation.
Who would be around to listen, or want to listen to what someone who needs to be at those places has to say. Not the general public certainly, the people who are in those places don't have a firm grip on reality.
The phrase speaks most about the person saying it when it is false, and it is false here, and the fact that you don't have sufficient reading comprehension, or have conflated good writing skills to AI, enough to realize that, is why experts on AI worry about people using and being exposed to AI.
You might find the follow of value, especially the discussion about AI and reality in the latter.
