indyp, this is basically what I wanted to say, too.
Technology does not revert backwards and the skin company now - Valve - won't stop it. AI is here to stay, whether people like it, or not. Millions are already using it, since at least like 2 years (GPT-4 was released in March 14, 2023). Now, more and more people and companies are moving to hosting open-weight LLMs locally for privacy, amongst others reasons. On artificialanalysis.ai you can see how open-weight LLM models are catching up to the proprietary ones. More about local LLM models hosting here: reddit.com/r/localllama.
In the worst case, game companies simply wont disclose AI usage. In the past, many jobs were replaced by technology.
Just let people decide if they like the game at its price.
