I supoose it depends on how its implemented. Mental healthcare is less accesible than ever while at the same time the population is being squeezed in a way where most have less energy than ever before in recent memory to deal with other peoples emotional labor. This means AI might be a useful tool for helping people feel heard and supported, which is often enough to get people motivated to make a change. However, if capitalistic interest is behind it I anticipate it will result in a product that holds your short term mental health hostage through a subscription service randsom. The problem isn't Ai, it's profit incentive in a field which is inherently perverse to profit from.
