AI is not ony about fake images and videos as presented mostly on social media. I do not know exactly where AI is being used but my son uses the ChatGPT 3.5 (free version) to solve complex math problems. Sometimes he does not how to solve a math query, he paste the whole question to the chatgpt and AI not only tells the correct answer but also show all the steps done to get to the answer. In short, he doesn't need a tutor to solve math.
This is just a very small usefulness of AI, it wil be just life chaging when deployed in Industries and business and DeepSeek made it cheap accesible to everyone.
