If you were in early 20's, what 5 things would you deem most important to work on to help the world?
But for fun, here is my list:
•AI
•Biotechnology, especially anti-ID and anti-aging.
•Energy
•Better governance
•Education
I didn't know what this was, and I was idly hoping that this was somehow about making biometrics not work. :-)
It turns out to be an idea in immunology:
