End of an era.
It's doubly sad given what's become of MIT Econ. There was never any replacement for the likes of Solow and Samuelson. Daron Acemoglu is no Paul Samuelson, and Olivier Blanchard is no Robert Solow.
Acemoglu’s graduate growth textbook is a horrific joke. Blanchard’s undergrad Economic textbook is rife w/ errors, grammatical and factual. Samuelson sweat blood when he wrote his textbook, Blanchard looks to have outsourced the writing of his to India.
