Plus, 24/7 access isn't necessarily the best for patients. Crisis hotlines exist for good reason, but for most other issues it can become a crutch if patients are able to seek constant reassurance vs building skills of resiliency, learning to push through discomfort, etc. Ideally patients are "let loose" between sessions and return to the provider with updates on how they fared on their own.
He or she has a daily list if clients, ten mins before they will brush up on someone they doesn't remember since last week. And it's isn't in their financial interest to fix you.
And human intelligence and life experience isn't distributed equally, many therapists have passed the training but are not very good.
Same way lots of Devs with a degree aren't very good.
Llms are not there yet but if keep developing could become excellent, and will be consistent. Lots already talk to ChatGPT orally.
The big if, is whether the patient is willing to accept a non human.
One benefit of many - A therapist is 1 hour a week session or similar. An Llm will be there 24/7.
