I get the idea and I used to try and optimize my computer time this way - working in the park, working while walking, etc.

In the end it was just a hassle and a distraction. I’d rather have 5 solid hours of work and 5 hours of non-work, rather than 10 hours of an awkward hybrid.

The type of work indeed matters a lot, if you need any visual confirmation or have to look things up yourself it's probably not worth it. As a solo entrepreneur I manage my entire business workflow. Everything is accessible from an API, from accounting to my CRM to S3 storage or my PostgreSQL cluster. Tasks can be handed off between different agents to keep things separated.

Not sure when you last tried, but I feel I would not be able to do what I do today with last years models.
