The thing is, ChatGPT can give you a quick answer, but it says nothing about *why* you should believe that answer or how you're supposed to live with it. Philosophy isn't just question-and-answer stuff, it's learning to think for yourself, to question what you're told, to spot logical traps everywhere. With AI spitting out convincing answers even when they're partially wrong, you need *more* critical thinking, not less. A guy who can just copy-paste what ChatGPT says without asking questions is gonna get screwed pretty fast in real life.
And honestly, the real philosophical questions - what's a good life, how should you treat others, what's just and unjust, what does freedom even mean - those are questions nobody's ever gonna solve for you, not even some super-smart AI. You can't apply an answer handed to you by a machine to your own personal context, your values, your choices. Your son's gonna have to figure out for himself what matters to him, and philosophy is a tool to do that properly instead of just following what everyone else does.
Then point out to him that the people designing AI themselves have to think about philosophical questions - what's ethics, bias, responsibility. Without that, you've just got technology that reproduces the mistakes of whoever built it. That's exactly what philosophy is there to prevent.
