AI will give you an answer that sounds plausible - but whether it's actually correct, whether it fits your situation, or whether it even answers the right question, you usually only notice once you think about it yourself. And that's exactly where philosophy starts. It's not that there are no answers, but that the interesting questions only emerge when you realize the first answer is incomplete.
The previous commenter is right, but I'd phrase it differently: philosophy isn't nostalgic, it's practical. When you ask "does it make sense to do this?", you don't need ChatGPT's best argument - you need to understand what "sense" means to you, what your values are, where you're willing to compromise. No AI can do that for you, because there's no objective answer. AI can only help you sharpen your own thoughts if you question it.
The thing is: the more you use AI as a substitute for thinking, the sloppier your own thinking gets. But that's not a reason to drop philosophy - that's the reason to do it even more. Ask AI if you want, but then ask yourself the counter-question. Don't treat the answer as a conclusion - treat it as an invitation to conversation. That's how you actually get what you need.
