Could someone create a bot that used sophisticated lexical analysis and various other methods to emulate human conversation in a way that fooled people into believing they were talking to another human being? Yes, probably, provided they had the necessary background in natural language processing and related fields. But definitely not in mIRC script. You might want to take a look at the
Turing Test for more information about the theory behind the idea and also discussion about whether that truly represents intelligence or merely dynamic, but ultimately still
programmed responses.
Could someone create a program that was truly intelligent and conscious? Impossible to know without having some clear definition of what consciousness is. But in practical terms for here and now with the computers and technology available: No. And absolutely positively not-in-a-million-lifetimes could it ever be done using mIRC's scripting language.
