Your son wants to learn stuff and the computer helps him with that. People that want an AI girlfriend don't care about the knowledge and usefulness of ChatGPT, they just want to use it to feel less lonely. Not at all the same use case. Although I agree with you, it's kind of sad that a lot of people will probably use chatbots to make up for no human contact in their life instead of using it to learn stuff and/or to fix their code/excel/etc.
Wow! I'm an IT student currently living in Antibes, working in Cannes and with quite a few friends from all over the world working in Sophia. It's a pleasure to see people from France on HN!
