Overall, not really, since with a competent talking partner you also would get ways to improve your situation, and help with pressing matters. It might be good in the short term, but there needs to be more to be good in the long run.

My guess would be the same phenomenon that existed with ELIZA. People want to be heard, especially lonely people, and LLMs are pretty good at that, asking questions and acting supportive, by design.

This whole situation reminds me of that fact that some people hire escorts to just have someone to talk to.
