It sounds like they are trying to replicate Asian style rote learning and cram school in a way that's more palatable to western audiences. Rebranding rote learning and force feeding as spaced repetition and surges. Typical SV bull.
The fact that they've rebranded teachers gives me concern that they're trying to further devalue teaching as a profession (if that's possible) and remove some of the professional expectations and protections that teaching still has.
Rote learning isn't the be-all-end-all of education, but it's actually very important. You can't think anything interesting without knowing stuff to think about. Facts are important. Memorization is important.
