If he ever worked with a convoluted business and data layer with about seven layers of boilerplate code that needs to be written every time a new feature is added, I doubt he'd still be singing the tune that everything must be typed. Because typing all that is a chore, not a benefit.

But that being said, when learning something new I do tend to type it out myself to help reinforce things. Same reason I handwrote my notes in college.

But I'm not going to type everything all the time. I'll get carpal tunnel, and it'd take me a lot longer to get tasks done.
