I would wager if you put a newborn human to be raised in the absence of any physical human contact, but somehow taught them to read/write, and gave them access to a universal corpus (text only, no audio/video), or heck, even internet access with `curl`, and lastly dropped them into the "real world" at age 25, they would be utterly incapable of performing, say, a basic service job at a restaurant.
Words help us symbolize and reason about our sense experiences, but they are not a substitute for them.
