It’s a cultural skill, and the more of those you master, the better. Your brain benefits, too. 
That said, I’m more of a gourmand than a gourmet and enjoy a full mouth, so unless the setting invited the use of my modest chopstick skills, like dinner with Asian friends where everybody used them, I’ve always preferred pitchfork and shovel. These days, dexterity issues related to a medical issue provide a good excuse for my permanent retirement from chopsticking.
On a side note, my dad always ate pizza with knife and fork. When anyone tried to make fun of him for it, he just pointed out that he ate as much pizza as anyone else, his hands were clean, and he only used one napkin; case closed.
