May I humbly ask you consider a counterargument.

I think your intentions with this piece are awesome, I love "gamifying" a lot of my instruction too. But it misses out on the intrinsic piece. A good place to start looking for improvements, but not an end all be all.
Also, if you poke around most schools, the traditional models of "sage on the stage" actually are disappearing from many secondary education classrooms. Myself, I run a "flipped classroom" model for some students where I am a mere learning coach and they often teach each other. There are other awesome examples out there of instruction taking place like this. It's all about improving the mindset of a teacher. I am not there to teach, I am there to ensure learning takes place. This mindset is critical to any kinds of improvement in education, IMO.
Cool stuff, I will check that link when I have time!
