I find Android 5 to be kind of an epic fail. The tabs ui doesn't work well at all, and is actively broken in several regards. The Gmail app is just awfully full of weird broken missing lame type things. The entire Ux around contacts is kind of a freaking nightmare. Etc. It sorta just underscores and reinforces my belief that humanity doesn't deserve to get in contact with any "higher" alien intelligences. I would expect such beings to have explicitly walled us off to make sure our complete ineptitude doesn't get out into the wider universe in some disturbing virus like fashion. Maybe we could just sum up The History of Human Ux in a book titled, "When Stupid Wins"?
