I've seen people post results from ChatGPT with confidence only to realize they get another result if they try again a few more times (of course, they never bothered.) It's a statistical model, in which case the math can never be trusted entirely, or else it's just making an API call to a normal math library, in which case what even is the point? Either way, there are already better tools for the job.
Needing "sophisticated plugins" to do basic math accurately should send people running away screaming from these damned things. I'll concede they have utility but we don't need to abandon our minds, hearts and wills to them entirely.
