Even if my question has been asked and answered before, what would it take for the site to realize that the answer that references, say, React 15 from 2016 is not useful in 2025?
It's just unsustainable depending on the goodwill of users, especially when SO score means very little these days.
Edit : It might be very doable by AI.. But they would have to sacrifice their "no ai answer" policy. (maybe they have already)
On SO, it's often best if questions are somewhat version agnostic, and different answers address different questions.
Yep, this is their 'way' but what I think @fragmede is getting at is, how can you know your question will be redundant next week. I prefer the 'duplicate' idea, where the user actually links the old question and says "hey this didn't work because X Y Z", then (in most cases) people will engage with the question as it demonstrates a level of effort.
