I love walking, but this article really bothers me, so I'm going to get a little sarcastic. Am I the only one who finds this entire article incredibly ironic? The author is trying to defend "purposeless" walking, but which is actually very purposeful! The loss of 'purposeless' walking is seen by the author as a loss of Creative Thinking. We're so busy with other smaller tasks, we're not setting aside enough time (like we used too, in the good ol' days) to think up all our really valuable thoughts! It would be one thing if they highlighted the relaxation, health benefits, de-stressing, etc., of walking, but that is clearly not the point: rattling off a list of Great Minds, and their Great Achievements whom we would benefit from emulating. The point of the article clearly is not to get people to take more breaks or curb their their obsession with work. Really it's a sneaky backdoor lifehack sermon: you're not good enough or creative enough, and you should pencil in some mindful unstructured time into their schedule to boost your Really Important thinking output by 10-15%.
