AI has been paying of for decades, it is used in all industries for appropriate tasks.
Now it is even better we are doing stuff no one thought it could be possible and advancing our work.
Perfect use case is for things that are simple to do but take too much time to be economical for humans (ex. counting products, plants, trees, cars, disease detection...) and using additional data to make better decisions.
Generative AI (for writing text, coding,... ) is of course no where close to being useful, but it can interesting to try. It is just a toy, expensive one, but still a toy.
Thing is you also stop sharing and commenting and engaging with other users. If it wasn't useful they would pull the plug long ago, nothing technical is preventing them.
