Many magazines have closed their submission portals because people thought they could send in AI-written stories.
For years I would tell people who wanted to be writers that the only way to be a writer was to write your own stories because elves would not come in the night and do it for you.
With AI, drunk plagiaristic elves who cannot actually write and would not know an idea or a sentence if it bit their little elvish arses will actually turn up and write something unpublishable for you. This is not a good thing.
Is that a recent change? I feel like I’ve seen a fair number of dead links on Wikipedia, mainly on older unpopular articles
The archives aren’t automatically added to the reference text in the articles. There’s an IABot you can feed particular articles to that will add it to reference templates. Also, if the IA archiving fails to work, too bad. (e.g. how it can’t even archive Twitter any more.)
