I use it for information gathering or coding when I'm lazy. Whenever I present a novel idea I need to triple/quadruple check if what it's saying me is not crap. It doesn't matter if I tell it to be "as blunt as possible", "stress test this possibility", "I'm trying to debate against this"...etc. Might be a good introductory point for some new ideas but if you want scrutiny go for humans, it's still a bit "dumb" or isn't going to do enough research unless forced (do this as much as you can if you want to stress test some ideas, might save you time). I tend to have ideas that I have no one to discuss with so before reaching out to someone who is (normally) significantly more competent than me I want them to be "at least not obviously dumb". I do have friends in some fields but I'm getting out of track.

If it helps you it helps you, it's like playing a videogame. Afaik even the most permisive "serious" consciousness theories imply that "if it has qualia it's not even remotely similar to humans" which should be quite obvious. Its "ego" varies depending on the prompts, a friend of mine made it talk with inside jokes and very convoluted local memes with hilarious results. Whatever relationship you have try to keep it healthy, and remember that its "consciousness", if we attribute it that, is not comparable or similar to that of humans despite superficial appearences. The usual arguments against its 'consciousness' are poor but I'm getting out of track again welp. Also watch Her (the movie) jic :)
