Mathematics education is much more complicated than you expected, even though you expected it to be more complicated than you expected.
If anyone tries to tell you the problems of math education, educational technology, or capital-E education are simple, or that the solutions are simple, or that the people who don’t accept those solutions are simple-minded, kick the crash bar and don’t stop running. They’re wrong and none of this work would be very much fun if it were that simple anyway.
Ever heard of Veik’s law of commensurate complexity? He suggested that no model can simultaneously be both: simple, general, and accurate. It can be 2 of the 3, but not all 3. ‘Simple’ can be important, because complexity is difficult to manage. Particularly in a world where no one person can know enough to make an informed decision. It helps get things done. Just sometimes at the expense of the general and the accurate.
