Well, surely you don't expect to just take the generated stuff and use it right away? For logos you usually need something that some entity can hold the claim on, so you probably need a human touch in any case.
Admittedly it was one of several hundred I had it spit out for me. But the design was completely original and caught me by surprise.
I tried making modifications but everyone kept telling me they prefer the original exactly as MidJourney made it!
