Like the markov plugins (that we lack), try to randomly reply to what is going on in the IRC channel.
Also, respond directly with a GPT text when a user asks a question to the bot.
How to add personality to the bot is yet to be discussed but I guess it could be added with a small prompt.
For a better effect a couple of lines in the current discussion should be joined.
For interactivity, when a message reach pre-defined threshold of sentiment (T63), trigger the reply with a sentiment tailored prompt.
