How would the world look if we were expected to learn something significantly new every 4-8 years? That's what my world looks like, but at shorter intervals.

How would the world look if we were expected to learn something significantly new every 4-8 years? That's what my world looks like, but at shorter intervals. 11 years ago I was programming in C++. 9 years ago, ASP classic. 8 years ago, perl, and for the last 5 years PHP. Just like doctors and nurses have continuing education requirements, so do hackers!
