It’s a machine learning chat bot, not a calculator, and especially not “AI.”

Its primary focus is trying to look like something a human might say. It isn’t trying to actually learn maths at all. This is like complaining that your satnav has no grasp of the cinematic impact of Alfred Hitchcock.

It doesn’t need to understand the question, or give an accurate answer, it just needs to say a sentence that sounds like a human might say it.

You cannot do that with other social media.

Facebook likes, Twitter likes, Discord reacts, LinkedIn reacts, etc. are all publicly visible. The only possible slight difference with this is that in some cases people might not be aware, in which case the issue would be that it is less obvious to a casual browser than Facebook’s “AncientMariner and 23 others liked this post” rather than that the likes are visible at all.
