y'all really folded for ai usage just cause "oh it's only for concept" which is exactly the inch companies want to eventually use more and more ai lol
imo using ai tools like this is fine as long as it helps the devs ( it's optional), and it'll get normalized over time anyway, same way AI coding tools went from "bad quality" to "cheating" to standard in just 3 years once people realized how much faster they get things done with it
because unfortunately whether people wanna accept it or not, we (including game dev studios) either adapt to these tools or get left behind EVENTUALLY
and there's a VERY high chance your favorite app, website or game was already assisted by AI, this isn't new.. studios across the industry (EA, Embark, NetEase, Ubisoft, Activision, etc..) already use AI tools, fortnite is just one of the first few being open about it & how exactly they use it
