TFA also refers to just Einstein's 1905 papers. He published general relativity 10 years later. And after GE he contributed e.g. stimulated emission, Bose-Einstein statistics, Einstein-de Sitter cosmological model and the EPR paradox, among lots of other stuff.
Also the claim "toward the tail end of Einstein’s life, he argued strenuously against the concepts undergirding the emerging field of quantum mechanics" downplays that Einstein was pivotal in emerging the field in the first place.
