Not per se, but if you're using it as a substitute for human interaction (like most 'chatbot' style UIs want you to), then yes, absolutely.

The main problem is that talking to AI is like talking to a human without any of the thorny parts. It's only going to be nice and helpful and always available to you. Chatting with AI is to social interaction like candy is to a balanced diet. Sure it's more instantly gratifying but long-term it's really bad for you. You need the thorny parts to build important social skills like tactfulness and navigating conflict.
