I have had many conversations with it in the past couple of months and it's so on point that at times, I forget that I was chatting with an AI entity instead of a person! It was that good. Topical, direct, and not talking around an issue but rather logical inferences and it made perfect sense. The spelling and grammar were pretty much perfect although I did pick up on one misspelled word (whether intentional to seem more human-like or not was hard to tell). The conversation left me shaking my head in disbelief at how very far we've come. It's practically indistinguishable from a human.
Perhaps that might be the one "tell"...that such an AI might be a bit too perfect in spelling, grammar and usage, unlike so many of my friends!

The scary part is that it's only going to keep getting better!
