Right... but the whole point Bloom's experiment is that if you give every kid a tutor, they perform (on average) at the 98th percentile. Not just the rich kids who can afford tutors. I do think there are valid concerns that this technology (like old-school human tutoring) could be disproportionately available to already-privileged children. This could potentially widen the achievement gap. But it seems way more likely that we can get poor kids a laptop to tutor them vs. getting them a dedicated human tutor.
