The walk is usually work too, just instead of staring at the screen and trying to think I take a walk and actually think. So when I get back I can provide input to the robot that will result in meaningful output.
Companies that pay people to hit enter instead of using auto-approve/bypass are going to lose to companies that pay people to think and produce results, regardless of how much time they spend in front of the screen or how many prompts they input.
Before I learned any programming skills, I worked with a bunch of great coders and learned a lot from them. I remember being impressed with the guy that would log on to start his day, but then sit back and have some coffee, M&Ms and read the Calvin & Hobbes comic strip from the newspaper (yeah this was long ago.) When I asked him about it, he explained that it was one of the important aspects of the life of a programmer to be aware of: if they are walking around the office with a distracted look on their face, you still want to sort of "knock" before walking right up and dropping a big issue or request on them, they might be doing the most difficult work of their day!
I eventually learned to code and would often find it to be my favorite part of the job--the looking out the window and planning the attack phase.
