Come on don't add your echo to the chamber of the nuisance of the IT industry which is causing a gatekeeping to brilliant talent from other fields. It's what actually causing a stale in innovation now.
Anyone with sufficient study and grit can master those and come up with excellent implementations. Now what I will consider too stupid is if I ask someone to prove that "knowledge" to me in less than 1 hour.
[Disclosure: I am learning and working on those algorithms on a pretty much daily basis, just from a perspective of broadening your thinking & logical skills during your learning curve (Why we need to learn Pythagoras theorem, if we are not going to ever use it?: https://www.facebook.com/watch/?v=10154359309646005 ) they don't serve many purposes except developer's ego. Not to mention that there have been better implementations of these algorithms out there. And you can always pick and choose.]
P.S. Life would be easier if you just bit the bullet and finally learned those algorithms. It ain't that hard.
