What? Whaaat? I am glad this is the first thing they immediately brought back, and while I am glad someone is doing some experimenting, this seems a bit obviously wrong headed.
Mentorship is the main way I see experience and knowledge are communicated (in terms of learning, besides making a LOT of hard mistakes yourself) unless you have the most amazing ways of teaching people already 100% completed and available for them to pick up.
To eschew mentorship almost seems to eschew the basics of how humans work!
