He I believe is a cancer patient (M1 colon cancer) and I'm sure he's intelligent and has a good story.
I just don't agree with his policies nor do I think it should be a keynote. I think if *insert a number of major cancer centers* were really serious about helping impoverished minorities they'd take medicaid. They want to tawk (shout out to Nassim Taleb) about it instead or mandate antiracism/implicit bias training with zero data that it helps (and it may hurt).
His stance is what some have called "racism of the gaps" (derived from the position of the "God of the gaps" that says everything we can't explain in science can be explained by God). Kendi/Critical race theory would allege that all differences in outcomes are mostly (?or completely?) due to racism (structural or otherwise) and cannot be explained by other factors. Others on the other side would claim that cultural differences or poverty may be more important determinants. Others would claim biology ("protoplasm") has some play here - though that is a very dark take on things.
I expect his keynote to be likely compelling and entertaining, but when I took a deep dive into his work, I found it not appealing and borderline dangerous (a government funded institution that "monitors policies" and is "empowered with disciplinary tools" for whatever they deem racist). As noted above, other academics that I read have grave concerns about him and critical race theory in general. So I'm obviously biased by their takes.
