Are there any companies or research projects trying to develop drugs or brain implants to improve general wellbeing? Not like anti-depressants or other medicine to treat specific disorders, but something that everyone could take all the time to rid themselves of negative emotions and live happily ever after. Something that cures hate, envy, lethargy, sadness, boredom. Something that finally makes one content with what they have. That would seem to be the ultimate technological achievement. Everything else humanity has achieved is basically just indirect attempts to be happy, so why not go at it directly. instead? Yet I hear almost no news of such a research front.
