I often arrive at this same conclusion, and I find it depressing. I find it difficult to sum up the feeling beyond "losing faith in humanity".
Try thinking of it this way:The closest living species to humans practices casual rape, murder, and infanticide. There were closer species, but humans likely hunted and raped them to extinction.
With these humble beginnings, it is amazing that most people can walk down the street safely (and that the street was built at all). More than 7 billion humans now live on this planet and for the most part peacefully coexist. Life expectancy and quality of life has never been higher and violence has never been lower. These metrics continue to improve over time.
Viewed from this perspective, issues of crappy UX seem insignificant.
Hope this helps
