I hope it was meant as, "We want you to have a bunch of techniques to draw on, not just the first you learned", rather than "Onleberyy Current Thing exists, don't be a peon doing last week's fad".
I keep seeing people apologize for delicious but visually unappealing meals, and I think amateurs can pick up a few simple techniques/ingredients to add colour or texture. For sauces I like
squeeze bottles and drizzles (surely very 2000 & late), but recently grabbed some little side cups as another option.
If I went to dinner at a friend's and they did the yin-yang spoon swipes, I'd be impressed.
