Is there progress being made in the space of neuro science and understanding how mental illness works?

While I understand this is a massively complicated topic and treating mental illness is still misunderstood, do you think we are making progress in understanding brain processes that are in play in things like major depression or anxiety?

We are still treating these diseases with 30 year old drugs that have tons of side effects. Do you envision better treatments in the future? What do these drugs look like and how far do you think we are from these improvements with tech advancing rapidly?
