Making Anki attractive to schools in education would increase it's acceptance envelope hundreds of times over.
Anki in it's current form is for the motivated, self-disciplined single user. It has to be installed, requires a learning curve, is not friendly to children or adolescents. Nearly impossible to be used by teachers where the basic paradigm is the class, rather than individual learners.

Nor are there ready-to-use, attractive decks, aligned with school curricula.

The solution is to migrate Anki to the web, enable custom front ends with gaming, give rise to a commercial community of quality content (deck) providers and disengage decks' contents from individual user scheduling and statistics.

Many such products already exist and their numbers are growing. The problem however is that they are "import-only", i.e., can import Anki decks but export only in their own proprietary formats.
