The whole Marketing industry got founded by the nephew of sigmund freud, after mass production started just 150 years ago, for the whole purpose to make you feel bad, unless you don't spend your hard earned Money on some BS that you don't need, because without that BS you feel like an ugly loser. Our whole Movie/Music Business is build that way. But back in the days there where Mass Media hence Mass Marketing. Now we have personalized Marketing thanks to Social Media. Now they can fuck us up for good one by one. That is just what we see happening the past decade.    Consuming goes up, Depression &amp; medication misuse goes up.  <br>Ask those Psychologists working for Facebook and Instagram etc.<br>Don't get fooled by this Silicon Valley Technology Mumbo jumbo. If your app has Marketing potential in some way or form it will sell. The Technology is not relevant.
