Stockfish is not too materialistic and the problem is in the search and not with the evaluation.

Most of these Youtube videos are "click bait".

Oh, look how stupid these engines are.

The authors don't know anything about how engines work and as the topic suggests, aren't really interested in showing how easily "solver" engines can find these hand picked positions.

When I run across these type of videos, I usually try to comment and educate the author/viewer a bit, but it usually turns into Charlie Brown parent conversation, you know, "Wa wa-wa wa wa".
