Hi Misanthropy

I can understand why you feel the human condition is so painful. Particularly with depression. I can personally say that when depression was at its worst the human condition as I experienced it was little better than a torture chamber. However, as I got some grip on depression. The quality of life improved somewhat, so that now things are a bit better.
Transcending the human condition is quite difficult. I believe the only people that have done this successfully are Buddhist monks. And I would think that in the US there are Buddhist foundations where people can go for a sufficiently long period of time to experience this state. I do not feel that technologies such as you mentioned will transform things for us in the foreseeable future.
For us the human condition will be what we can make of it by getting a grip on depression, having a meaningful purpose in life, such as a charitable cause, or reconnection with things that fired you up in earlier times to give meaning and fulfillment.
You are quite right in saying that political leaders psychiatrists and psychologists are not dealing with all of the problems that make the human condition miserable. That is because they see their remit as being enabling patients to get control of their depression so they can have a better life. And with that better life perception of the human condition does change somewhat to a realization that life is really sunshine and showers good and bad times. That a lot of things wrong in the world is really not within our power to alter. What is in our power is to reach out to a lot of other people and try to make them feel better thus making a difference.
The only thing we can do to improve things generally is to support those movements that advocate for better human conditions.
For me, one of the most profound philosophical statements was made by Voltaire, who said we must cultivate our garden, which in fact means we must do what we can to improve our own human condition, and that of other people and we can make ourselves do that with what free will we have.
I would have to agree with you when you say that you feel you are not the person you could have been. That is so true. Because of depression, which is a really great obstacle to achieving full potential. However, the option remains with medication and therapy and persistent effort on our part to get control over depression so that we would then be in a position to move toward realizing some of our dreams and objectives. The past is history and focusing on preparing for a better future is all that can be done. Take care. I hope and pray your life experience will improve significantly in the future.
