As technology increases our suicide rate isn't really consistently declining. Our prison population has increased. Technology cant make those improvements alone. We need improvements in governance, culture and education for this to happen.
Technology can be used for good or bad. By itself, it is just a tool, it's up to us to decide if we are going to end up in a police state with constsnt surveillance and tyranny, colonize Mars, create weapons that can wipe out most of humanity, solve healthcare problems, etc.
