"I’ve never been able to prototype product on the computer; it always felt too clunky, too slow. Similarly, if you are in a meeting or—as I noticed during Y Combinator at a talk—typing on a laptop seems like a sure way to miss 70 percent of the content. I think typing encourages you to write more, to write for the sake of writing rather than for taking notes."

Your TL;DR skipped over a possibly important thought to many people.

Do people need to be told everything? I mean, they really can't figure out for themselves if they should rather use pen & paper or a computer for prototyping?

Even if somebody tells them, shouldn't they still try for themselves? Maybe it works for the person who tells them, but not for them?

No one needs to be told everything. But everyone needs to be told something.

It was only a couple of years ago that I discovered the benefits of writing on paper vs. computer. I needed to be told, back then.

No. But I like reading about personal experiences and the little details.
