Using AI for content creation without a major input from the human creator behind the account is not looked upon with good eyes on Hive due to the limited pool of resources to be distributed for "proof of brain", not for "proof of using an AI" (although, I suppose that's a kind of proof of brain).
Personally, I don't have an issue fully AI generated content, if rewards are declined, burned, sent to DHF or if the account is known to create AI content (for example, by mentioning that in the author description or in every post).
I've seen it used, declared or through my own perception, to improve the structure of the post or change the ordering of ideas (sections), to fix spelling and grammar mistakes and rewording your text to make it easier to read, or to replace words with more distinguished synonyms and different ones.
Until now I haven't used an AI to improve my posts, although I know they can be very good at that. I preferred them in the raw form, even though I use a spell checker to not have obvious mistakes.
What I do use AI for is to speed up my content consumption. There are different ways to do that, from basic translation from other languages, to creating quick recaps (the AI takes care of translation first) or other types of extraction of essential information from a text. You can find these and more on PeakD, if you didn't know.
Something else that is still in the content consumption area is using AI-generated threadstorms to quickly go through more news on particular topics and only expand what you are interested in. In my case, for crypto, but there are other topics, like business or life and I think, sports. Probably the number of topics expanded or changed since the last time I checked them out.
But I've seen more uses of AI on Hive. From AI-generated graphics for games (Ragnarok and possibly others) to mini-scripts created by AI - I saw one such script created as a helper for Golem Overlord, to clear/hide unwanted targets from the list.
There may be elements of content we are not aware is AI-generated. For example, Khal talked about a plan to link LeoGlossary terms into a post using AI to make the associations. There were more details shared, but this is not the place for them and I'm sure they'll change several times from then to implementation and then to release. This could be an example where the average user may not be aware AI is used to make those connections and yet will use the new feature, when it will be available. As I'm sure some users don't know those news threadstorms are created by AI either, since I sometimes see replies (threads) as if you talk to a person.
AI will soon be so embedded in our lives - whether we like it or not - that they will be much like smartphones. Become indispensable. Get ready for that because that time is not far away.
