It comes off a bit verbose and hand-wavy.
My view of GSEs:
- Wiliness to test hypotheses, listen to others, seeks input and feedback, and maintain metrics to decide if various methods are or aren't working.
- Minimal ego.
- Curiosity about things at lower levels.
- Mastery of first principles and able to create data structures and algorithms optimized for specific, difficult problems.
- Ability to debug up and down the stack quickly.
- Concern for stability and usability by consumers of products and services maintained and delivered.
- Ability to teach and mentor.
- Ethical integrity refusing to compromise or exploit users for short-term business gain.
