Right. So what it really is is a copy paste machine that moulds what it pastes slightly to make its patchworks fit.

So either you prompt engineer it to present your own opinion back at you, meaning it's not an effective sounding board.
Or you don't prompt it to match your bias and it's now copy pasting the average of reddit. Meaning it's not an effective sounding board.

My advice is to use it as a sounding board often, if only to lose respect for it. Do it with some stuff that doesn't matter.
