Why does it matter?
Treating most mental illness would change daily life for hundreds of millions, not just clinical medicine.
Direct quote
It is my guess that these four routes of progress working together would, as with physical disease, be on track to lead to the cure or prevention of most mental illness in the next 100 years even if AI was not involved - and thus might reasonably be completed in 5-10 AI-accelerated years. Most mental illness can probably be cured.
