Of course the inherent meaning in the statement is that a large portion of these things do suck, for most people.

I find it telling that most people who start an online course never finish them - why? The experience isn't worth it.

Just like a video call hasn't replaced person-person interaction, nor can an online course truly replace an in-person class - so many more things happen in the classroom or at a university than at home. There is intelligence in human interaction. This is what silicon valley misses.
