I see a lot of ads for girlfriend chatbots, either blatant or with all kinds of thin disguises (the last ad I remember was a "personal assistant who will do anything", but "therapy" is also a popular framing). In comparison I barely see or hear anything about professional not-sexy therapy chatbots.

I imagine if you go to psychology conferences you get exposed to the professional side a lot more, but for the average internet user that's very different. I wouldn't be surprised if the AI girlfriend sites had many, many orders of magnitude more users
