One thing I struggle to address myself is — whether things like Candy Crush Saga are useful to humanity or not? Whether I should spend time on working in healthcare and education (which I do) or making the next camera app cos it wont make the world any better.
Then I think of multi-billion dollars entertainment industry and most of it makes stupid stuff, and makes money cos it helps people kill time. I don’t find much difference.
I personally might not work on these things, but I resist to blame people working on these things, unless I blame the entire entertainment industry.
