I can't provide a theory of everything, but I can predict the future:

- The application paradigm will come to an end.

- All apps will be replaced by a general purpose interactive language.

- We will realize NLP doesn't work.

- 80% of software jobs will disappear within the next 15 years.

- Privacy will be revealed as foolish and selfish.

- Transparency will become the norm within the next 30 years.

- Money will be replaced with a social score/currency. Honesty, consistency and predictability will be the most valued traits.
