I'm a top 10% student that goes to a top 30 engineering school. I haven't gone to a lecture or bought a textbook in over 2 years. My grades haven't suffered - they're mostly a function of time spent doing homework and going through the lecture slides. For undergraduate students - a physical college is now mostly unnecessary (excluding some lab work). Research students - not so much. Another thing. Arguments against any new technology saying "Oh, but you can't replace that!" are always going to die. Lowering the cost of something by a factor of 100x changes everything.
