The argument in the story is in the first line: "Coursera's market debut is proof that the future of education is online." It is of course no such thing. The markets follow fads and rumours, are fickle and irrational, and have a history of making billion-dollar mistakes. Just ask the people at GameStop. Still, Coursera's chief executive Jeff Maggioncalda has a point when he says "we all will not go back to offices, we all will not go back to campuses. And so, online work and online learning - among other things - are here to stay." True. But they were here to stay before Coursera's IPO, and indeed, before Coursera ever came into the market.
