Endurance cuisine spreading via social media is quite silly but I did want to provide a brief counter example. My SO and I are lactose intolerant so we make occasional big batches of cheese at home - given that we're doing this if we're making lasagna or calzones we'll often set aside a portion of the cheese to tune it to the right moist/dryness level and that makes a big difference in the final product.

Knowing how to make homemade cheese and applying that skill economically when it'll make a significant difference in the final product is useful... that ends up going with a home made puttanesca sauce instead of some canned pasta sauce... but those two end up covering some store bought noodles because I have priorities about my time.

Much like a lot of we programming folks learned the basics in university (assembly programming, building basic data structures in C++) comprehending the basics can let you make a judgement call on when it's appropriate to put in the extra effort. Someone who has never cooked a load of break may find that task daunting and insurmountable... but someone who regularly cooks fresh rolls for their daily grain and just keeps a weeks worth of dough in a tin in the fridge can whip up fresh rolls for dinner in a matter of minutes.
