What your current title?
I would love to hear answers to the following:
1. What ideas proved useful throughout your career, and what ideas did you change your mind about?
2. What are your hobbies? Do you still program in your spare time - if so, what? Or do you find other outlets?
3. What went into the decision to go back to school? Did you get the PhD? If not, did you get burned out, or what lured you away?
4. What were the Big Ideas in software over your career that didn't work out? Any that were better than expected?
5. General successes/regrets/advice for these readers!
Any advice (technical or life) for us younger people?
[I'm more than halfway to your experience but definitely missing this aspect.]
