Ehh, I think it’ll be a looong time before machine learning can make meaningful character interactions.
It may be able to make maps faster, slightly better versions of something like No Man’s Sky or Minecraft (both already sporting functionally “infinite” procedural generation), or fill a city like Cyberpunk 2077’s with slightly less mindless wandering NPCs, but I don’t think it’ll help make story-based RPGs bigger in a useful way
The NPCs that stand out in an RPG do so because they typically have a well-crafted, and finite, story arch which is incredibly difficult to do with machine learning and trying to make things more procedurally generated.
I think you missed the entire premise of the article you linked - the “stealer logs” mean someone logged into your account on a system that had been breached (infected with malware), and the “stealer” “logged” those credentials.
Also, SteamDB and Steam are two very different things. SteamDB is an independent third party offering that just tracks Steam data via their API.
