Being pedantic here, but knowledge is equivalent to understanding (information being knowledge without understanding). Wisdom is the word you were looking for (knowledge being wisdom without experience):
The New Grad had knowledge. The Senior Dev had Wisdom.
I see it differently. Knowledge =/= understanding. There are plenty of ppl who know a lot but have little understanding.
Put another way, knowledge is the nodes. Understanding is grasping the connections. Understanding is the higher power. Understanding is where the magic happens.
Wisdom? Wisdom is next level understanding. It's the maturity of developing connection within the connections.
The New Grad had knowledge. The Senior Dev had Wisdom.
Wisdom > Knowledge.
