Perfectly within the range of known AI capabilities.
To recognize a bot, notice what they CAN'T DO.
For example, BO ABOLUTELY CAN NOT break the character he portrays here. This awkward, "chan lingo" cussing and berating– that is ALL that BO can portray. There will never be a moment when BO "shows another side of his personality", because all he is is a bundle of algorithms, and constraints on AI impose serious limitations.
