Which?

snippy little bellend

so your explanation is very clearly incomplete.

You’re just going to lob useless comments like “Interesting perspective”? OK.

Amazing, you came up with something worthwhile

Are you practicing accusations in the mirror technique, I don't understand. Do you really not realize how aggravating your discussion approach is? Do you really expect someone to see your first comment and go "oh what a lovely reply, let me get into a very interesting discussion with this person"? Are you really that not self-aware?

Your prior entry point to the discussion was claiming that I was somehow trying to prove that sentiment about life is the one and only explanation of declining birthrates. Now that you have admitted that you were wrong in assuming that (I assume you did otherwise there is no point in discussing further because we are discussing something fictitious), lets go back to the crux of the discussion:

I am claiming sentiment about life is a more major contributer to declining birth rates than AI chat bots. And you are asking for proof or evidence of this? If you only accept as valid proof a carefully designed study that compares AI chat bots and sentiment about life for this particular question, I would only laugh at this expectation (mostly because AI chatbot romantic relations are relatively new and this is an original claim about them effecting birth rates so very unlikely for some researcher to have taken up on it yet).

Currently, the only reasonable way one can compare the two is to see if there are any sources that independently claim they are contributers to declining birth rates (or not). I have presented multiple source for the first one (and have read more in the past). For the latter I don't think we will find any sources, but it is biased by the fact that it is a relatively new concept and people may not have studied it. In such a scenario the only reasonable action then is to default to logic and that is what I did. From my previous readings and my own perspective I think sentiment about life affects birth rates. From reasoning I imagine people get into serious relations with AI chatbots because they want to lead a life in isolation from Earth, they have stuff they feel like are missing from their life (hope for future etc) and they look for comfort in a chatbot that always confirms what you say, bigs you up no matter and presents minimal friction. So for me it makes more sense to view it a side-effect of again sentiment of life rather than an individual causative effect on declining birth rates. If true, this would mean because both declining birth rates and increase in chatbot romantic relations are caused by decreasing sentiment in life they may indeed be correlated but do not cause each other. And hence makes sense why someone who hasn't thought about it deeply may think it is causative.

You have not contributed one bit to this discussion apart from aggravating the OP (me) and pulling the discussion in completely the wrong direction while trying to present an aura of the superior unbiased debater. lol.
