I've always wanted to work while walking. Years ago, I read Stephen Wolfram's blog and saw that he had already been doing this for years.
I felt inspired, but walking around with a laptop strapped to my waist didn't seem very ergonomic to me. Besides, how was I going to focus om the details on my screen and not walk into a tree? Also, working on a complicated code problem while working short-circuits my brain: I either automatically stop working or I stop thinking. I quickly gave up on the idea.
But things are changing fast. It is now possible to do a portion of the work while outside. Whenever someone sends me something long and complex to read, I will listen to it as a podcast with NotebookLM or have a discussion about it with ChatGPT. If I need to write a report or prepare a meeting, I will ask an agent to interview me until it has all the necessary information. When I think of some code change that needs to be made, I open a Copilot agent session via the GitHub app and ask an agent to start working on a PR.
All of this happens on my phone and my AirPods. No weird laptop support straps required. Walking while working definitely doesn't feel like a gimmick to me anymore.
