While there's great truth in these observations, I think an important point is being overlooked. When you see "lab" experiments like
this crowdsourced RNA folding thing being performed, shouldn't we anticipate a point where you choose students who are familiar with these online approaches and eschew those who know only how to operate a scope? And do you trust somebody's ability gained from being in some physics lab class where you don't know what they contributed (maybe their lab partner did all the scope work?) or is it better to have a certification in operation of a scope gained through a VR simulation of the equipment by its manufacturer? And maybe six other pieces of standard equipment as well? We're not there now, but that's where we're going.
When the time comes that a large number of people on the committee do have experience with MOOCs and other forms of non-traditional education, then won't they start to favor people who come in with that background? Won't they prefer people with the initiative and self-sufficiency to forward their own education rather than those who just go down the standard path?
I'm not saying that this time is here now, but aren't we heading in that direction? Won't it be the case four or five years from now that our decision space will look different? Ten years? Sticking with what you're comfortable with and understand well is a sure path to obsolescence.
