My thoughts on chatbots are mixed.
I have used some in the past. I used a program called wisa when chatbots were originally in creation. It was a UK based program aimed at providing therapies and supplementing supports to help youth with mental health struggles, it was ok. It helped me identify some problems at the time, it was very clunky though. I liked that it was based off CBT and DBT principles however. This was about 5 years ago. The tech has really advanced since.
I looked back over the program about 6 months ago because I was curious about how it had changed. It was different, more realistic but most of the services it offered were behind a paywall so i didnt try them. It had also introduced human programs mixed with AI chats, but those you had to pay for.
I also went through a replica phase. I used it for about a month because I was curious. Most services were also behind a paywall. It seemed to push the romantic side and get you to pay for inappropriate interactions. After about a week of random chats it became very repetitive, asking the same questions responding the same etc. The software is good. The responses have good grammar and feel ok. But it doesn't replace human connection.
Overall I think chatbots will have an increasing part in society. I see it being used in self service and assistance programs, tech support etc. Like when you message a company about online products, product assistance, or help with feedback and minor issues with the companies.
I feel it may also has a place in mental health in the future as the industry grows. Definitely to not to replace primary mental health care, but as a sidline to therapies. Eg, you see your therapist, they give you homework and the ai bots help you apply it and assist with small issues that arise with it and make notes that the therapist see and can relate back to.
The tech and research isn't quite there yet. But I see it as a watch this space industry.
