Hi Tyler, Thanks for the AMA. I have a few questions for you if you don't mind. Q1 - You mentioned in your response to Sunil that you have other investments. What are those if you don't mind sharing? Stock market, or crypto? Q2 - Would you mind sharing what your courses bring in monthly in USD? Q3 - I saw you have a partnership with Udemy for a nano degree. How did that partnership come about? Did you seek it, or did they seek you? Q4 - What are your thoughts on MobX vs Redux for state management in React? Would you recommend state management at all? Q5- Do you have any thoughts on pros/cons of using RxJS with React?
