Aren't the general background, innate abilities (or inabilities) related to the learning skills, expectations or commitment of the individual student and the training, background, and teaching skills of the instructor the same? Apparently anything can be put online, it is not precluded that everyone should or will succeed who takes an online course or that what is learned is any better than what is delivered closer by other methods. Technology will improve for delivery but it may not change the learner.
