Does Sneed posting have moral value?

Not really no, most of those posts are a mix of math with blogposting. I could post dozens of them here from the last two threads and in this one they've gone as far as to post a picture of themselves to get attention.
>We also discuss aspects of being a math student or researcher in /mg/, it has never been strictly pure mathematics.
That's welcome, what's not welcome is when your post is 70% blogposting and 30% actual mathematics/math life/research life.
>If you really thought like that, you wouldn't even post unrelated picutres like the anime pic you sent
Lol
>you're just annoyed because it rubs you the wrong way.
Oh, and how so? I literally didn't get what you tried to imply here.
>Just ignore and scroll.
Great way to excuse criticism. I guess all off topic posts should be allowed now, after all one just needs to ignore and scroll, am I right?

It is a useful thing, sure. I use it almost daily when working on stuff, like for example how adjoints and limits commute etc. (say, you want to suspend a wedge, do you get the wedge of suspensions back?), so I have nothing against category theory per se. It's just the almost religious way people approach it, trying to turn everything into a manifestation of the Yoneda lemma and so on. It does obliterate quite a lot of unnecessary steps when one knows when to invoke some categorical results, but to know everything only in the macrocosmic way is not good in my opinion. That's what I meant when I gave the extreme example of defining the cartesian product as just the categorical product in the category of sets and functions. Sure, it is that, but if the student has no idea what it would be classically, then that seems like a pedagogical misstep. That foundational remark is true. I'm not interested in foundations themselves, but I think it is still important to at least mention which axiomatisation is being used. Sticking to certainly small categories is my way to avoid such problems.

That's what was claimed in the paper I was reading. That's when I decided that applied folk can apply their stuff without me having or even wanting to know.

Does the space of wolves have isolated points?

If humans suddenly disappear, what will happen to the internet and all websites when no one is booting up pages? Does it stop existing? Where would it all go?
