Depends on how you define AI. Aren't Youtube, TikTok, etc. serving content based on ML recommendation?
In the case of recommendation systems, the unconscious consumer is wholly unaware of the witchcraft occurring on the backend.
OpenAI's ChatGPT, Midjourney, HuggingFace, and their kin, are commoditising a technology that was historically resigned to hidden artefacts, whose input was limited to system calls, not user calls.
But they don’t directly show you generated text because it’s still kind of whack.
This must be new, right? I noticed this too and to be honest, it immediately improved my search experience, which had gotten very bad.
