Being unhappy and unsatisfied is the main reason we have the technology that currently exists. If people were satisfied traveling by horse, the automobile wouldn't exist. If people were satisfied with 480p, the HD television would never have been a worthwhile venture. Being continually unsatisfied is what causes us to strive higher.
I never said any of this technology enhances our level of happiness. I just said as a species, being constantly unhappy could be one of our greatest strengths. Otherwise, we might be sitting in a cave, smiling at each other until an asteroid removed us from existence.
Regular people may have been satisfied, but the military wasn't, who drove almost all of the research into the 80s. The consumer market is just a follow-on to that, where choices were presented to "me" as better.
There is a world of difference between freezing in a cave and developing 1080p/2160p/4320p.
However, to survive as a species in the long term, we need to leave this planet. To do that, we need a number of advancements in technology.
So, if we can agree the survival of the species is in our benefit, then we can agree development is considered a good thing, even if it doesn't equate to an increase in happiness for the individual.
