I interpreted the post much more broadly, way beyond software tools. There are tons of things in existence outside of computers, and each of us is a noob in most things. Just some examples that come to mind: Playing musical instruments and singing, yoga poses, barbell training with correct form, Buddhism, how to negotiate in an Arab bazaar, tax returns, training animals, riding a motorcycle, how to navigate forests, how to navigate the sea on a sailboat, how to direct and edit a movie, reciting poems, how to structure a novel, cooking and baking well, brewing beer, how the electric wiring works in a house, hobby electronics, how to build furniture, how to shoot guns and how they work, self defense and martial arts, fixing a car, hunting and fishing, BDSM and fetishes, finance products and the stock market, law and the court system in various countries, foreign languages, diet and nutrition, amateur radio, physics, painting, calligraphy, psychedelic drugs, networking effectively with important people, being a bartender or other service personnel, backpacking alone, raising children... Some may say "I may not have much practice in [particular thing], but surely it's easy, it's just [...]", but I really recommend reading that blog post called "Reality has a surprising amount of detail", which shows how many things there are to learn about simple sounding special cases (like building a staircase). All these things and hundreds more are rabbit holes with more and more branches of rabbit holes of communities, cultures, various levels of expertise attainable in each branch and subbranch etc.
