I agree, people need to have bad times in their life to fully appreciate the good ones. Furthering the look into technological stimuli for happiness, I present this question: If people were always happy, would not art suffer? Part of the beauty of art in any medium, be it film, literature, musical, dramatic, or visual, is the connectivity with real and painful situations. People thirst for honesty in specifically film and music now more than they ever have historically. If technologies were discovered and made public to protect the human mind from "bad" emotions and keep them happy, would not art as we know it deteriorate? And with it, the beauty of human experience? Although happiness is desirable, I cannot help but feel it can be fully appreciated without a sense of sadness. True happiness must be achieved, not bought or taught, and therefore, I believe technological stimuli would only create a false happiness that would threaten to destroy culture.
