I am not sure if this sounds optimistic or cynical, but I think this analysis is overblown. Because to be honest, affirmative action never increased our numbers in the professional (medical, law) fields like it did corporate America.
Now it did get us into more prestigious institutions or firms or hospital programs and that helps since I have family members that benefited from that. But as far as getting MDs for example, not much ever really changed except more Black women became MDs (now at parity with men)

Proportion of Black physicians in U.S. has changed little in 120 years, UCLA research finds
I don't have the same data for lawyers but it is probably similar with the exception of bw having a larger lead on bm.
At the end of the day, we are going to have to reinforce our institutions (the 3 current and 2 upcoming HBCU med schools as well as the several HBCU law schools) and Black professional organizations like the National Medical Association and National Bar Association will need to strengthen their pipelines and informal networks.
I predict a larger percentage of the best and brightest Black students will be coming to HBCUs in the upcoming years so that will help us get them hip to game. There are also several med schools in the Caribbean people go to for lower MCAT scores and you still can pass Boards and practice. Hell, set up a med school ourselves down there, even in Cuba.
Gotta think out the box, our adversaries do.
