Glad to see some sanity for once and people that realize building 'trivial' apps like Twitter and Uber are not feasible 'in a weekend'. Just making sure the app is secure takes months, and security becomes more complex as features are added. Pretty much every feature you add to the app can explode the complexity exponentially.

e.g: a sorted timeline if strings is easy, but add the simple feature of 'retweeting' and being able to 'unretweet' for example and things quickly become more complex.
