I can imagine this sort of thing replacing drive-through coffee shops, especially here in Canada where drive-through coffee is ridiculously popular, and the lines are notoriously long.
I guess I'm just trying to point out that I think this isn;t exclusive to software jobs, but it's the same trend for any mental labour job.
Getting into, and staying in, a state of flow requires a high cognitive workload, and getting back into it once you're kicked out is almost impossible some days. It often takes me at least 30 minutes to get back into that state, if at all. I think our society needs to re-think how we spend our time at work,but unfortunately that'll require government regulation, unless companies that are bold enough to switch to a 6 hour workday actual start making more money than their competitors.
