You've always needed skepticism, of course. But it used to be if you came across an article about a super obscure video game from the early 90s (referencing the blog post here) you could be reasonably sure that it wasn't completely made up. There just wasn't the incentive to publish nonsense about super niche things because it took time and effort to do so.

Now you can collate a list of thousands of titles and simply instruct an LLM to produce garbage for each one and publish it on the internet. This is a real change, IMO.
