That's more the future than an AI being made/licensed by EA that creates Madden 2030 from nothing. Changing Madden 2029 into 2030 and updating the jnterface/visuals and making it faster/more streamlined and identifying places to add further content, creating that content, managing that content - all of that an AI system can do.
Yeah, lots of generic copy mobile type games are coming but this is absolutely going to be more than that.
Is Blizzard going to switch to AI in any particularly notable way? No. They're the premium brand and the whole point is that it's the higher-quality, higher-priced option (or, with how software scale works, they're higher-quality which they then aim to translate into more scale).
So yes I assume artists at prominent, quality-focused studios are fine.
That's like what, < 1% of total employed digital artists? For the other 99%, this is an armageddon. I'm sure nobody's dream job is to make the 934652352345th hot anime girl for generic gacha mobile game #235624563426, but it pays the bills and can be a stepping stone to jobs they might like better.
Software is already somewhat hardened against this because while there are (were?) plenty of jobs making generic hot anime girls, in software we'd just have 1 person made hotanimegirl4j and then we can all copy that forever. E.g. nobody is out there employed re-writing GNU coreutils over and over (is it a fair comparison to say that hot anime girls is to art as the ls program is to software?)
So yeah. I feel for these people who will be economically impacted by this. You can already see this in the patreon numbers of artists who specialize in certain types of content. People are getting their fix by DIYing it, and competition exploded since there's so many more people offering that content now.
