There's a small misunderstanding: when people talk about "“generative” AI systems such as ChatGPT, which can create content that is indistinguishable from human output."
The truth is closer to "“plagiaristic” AI systems such as ChatGPT, which can rephrase human-inputted content in a way that is distinguishable from its original human-owned source."
These are not generative and they don't create anything. They collect content written by experts (humans) who made it available for free on the Internet with the goal to reach other people, under the assumption that they would be quoted and referenced. The underlying assumption of the Internet is that people would provide free content in exchange of either paid advertisement or prospect of getting new customers, or with the goal of connecting to a community of researchers which will help each other. We are in the process of voiding the whole idea.
The change in paradigm is that ChatGPT does not respect intellectual property and rephrases the content in a way that cannot be considered as plagiarism in the courts. The long term consequence is that the people who produced content for free will stop dong so now that big tech are putting all possible effort to develop legal plagiarism at an industrial scale.
