Oct 26, 2020 at 4:33	comment	added	qk11		This is very helpful, thanks. Since you mentioned independence results and the Whitehead problem was also mentioned above, I wonder how I should think about such results in general, related to my question: I mean they are serious results on their own right, and presumably do heavily rely on set theory, but are they always the kind of result that the working mathematician (e.g., the group theorist) is immediately interested in? Or was the point of there being results out there that set theory cannot solve all the problems (in which case, still a good thing to know)?
