My guess is health and psychology, they get there by creating exceptionally good personal &quot;life coach&quot; bots.  Basically like the movie Her minus the FOOM.  I guess that is AI, but really it is more a UX problem, a truly engaging positive thinking bot doesn&#x27;t have to be too complex to change people&#x27;s lives. It simply needs to be so well designed that it becomes apart of people&#x27;s lives.  Design may be far from googles strength now but results are and if googles bot can improve my life that is all that maters.
