Some other fields (e.g. long-running academic research experiments) involve a feedback loop of months or years. I've done experiments where the experiment subjects (mice, human cells, etc) look exactly the same for weeks and weeks, and you have to work on them every day not knowing whether they'll turn into something useful in a month or two. Writing grants and papers has a turnaround time of months--you work so hard on it, lob it into the ether, and just wait 6 months to see if anything will come of it. Coming from a background like that, I find that the days/weeks feedback loop time in tech makes me positively giddy with joy. It's hard for me to imagine thinking of 5 days as a long time to work on a problem.
