Yes; the question should be reopened.
I read each of the questions noted as duplicates and also quite a few more on this topic(linked in my answer to the question) and I do not believe any of them are duplicates. I agree that a basic understanding of phase detect AF and contrast detect AF is important to have, but all of the existing questions do not specifically answer the question Why is DSLR autofocus much faster than Mirrorless autofocus?.
I answered the question here by explaining that Mirrorless technology has transitioned somewhat from CD AF to PD AF and that is why some confusion on the topic exists. Only having questions that point out Live View comparisons to DSLRs, or that are based on CD AF assumptions are not complete in answering the question at hand.
Breakdown of why each question isn't a duplicate:
Why are mirrorless cameras much slower than DSLRs?
Why is it harder to focus using LiveView?
What is the practical difference between phase-detect and contrast-based autofocus?
