"Online Courses Could Widen Achievement Gaps Among Students," is the headline over an article in the Chronicle of Higher Education reporting on a Columbia University study that frets:
students in demographic groups whose members typically struggle in traditional classrooms are finding their troubles exacerbated in online courses.

Leave it to Columbia and the Chronicle to find a downside to technology that increases access to higher education while decreasing costs.
