Plenty of time... the totalitarian principle of QM notwithstanding, not everything not forbidden is compulsory at a macro level; academia is not a deterministic machine for yielding studies given the appearance of a phenomenon. Otherwise I'd ask you to provide some studies quantifying "plenty of time".
I feel 13 years should at least be producing nonfiction essays or something that passes for journalism. It took 4 years for 5000 trump books to come out. 13 years for the upending of racism towards being against the whites should be plenty, too.
