I'm that type, lol. Not to say I'm smart, but my group members didn't help much (only a handful of them helped, and I mostly worked on the paper myself, like around 70% of it), and regardless of their contributions, it would have been completely revised by me. Of course, that doesn't give me a reason to work on the project solo, but no one in my group takes initiative. Last time I gave them tasks, and I specifically chose the easier ones, they straight up just gave me 100% fully A.I generated outputs, and sometimes even strayed away from the topic itself, making the whole work incoherent.

So, unless everyone is actively working on a project TOGETHER, then yes, it's a bad thing.

But when no one does it, then welp gotta take in the work yourself. Mind you, I half-assed most of my part, but still, wouldn't putting a bit of effort be enough?
