So does Don Knuth. So does Don Hopkins, the former director of health programs for the Carter Center and spent years leading the effort to eradicate Guinea worm. So devoted to his task, he didn't even give his kids his cell phone number when he traveled to Africa.

I can't speak for the current US President, but there are a lot of people who are perfectly capable of reading email, but for whom the task would distract them from more important uses of their time.

Don Knuth is 82 years old.

If I had the resources the president or a CEO had I would have my assistants print out my emails too and I'm 29 years old, knowing what I know about screen time and mental health. Its healthy to have some separations from technology.

Agreed. Less screen time is better and I am more thoughtful reading a physical medium.

Surprising that people don't flex to the President's preferred style of communication. If he clearly doesn't want an e-mail, don't send him one.

Sounds efficient to me. I hate reading, and it's painful. Audio is great.

At that level, this makes perfect sense. The last thing we need is a President screwing around for an hour each day with the latest software update, etc.

I think that's the exact kind of persona our president has been trying to pull off.

I don't think that's a persona - I think he really is that guy.
