Both of you speak often of how much time automations can save you in the long run which in turn legitimizes the up front time cost in setting these up. And I agree.
But another reason which I do not think is always the same is to save from decision fatigue. These are those annoying little things that are simple in and of themselves but that take up a small amount of your brain power but interrupt your flow. The difference is that here, it is not so much about the time saved, but not having to redirect your attention to some tedious mundane detail. Listen to the last bit of the latest ep of Cortex where Grey speaks of his podcast idea shortcut. His shortcut might save him about 2 seconds… but the import thing is that it puts the essential task of writing up front allowing him to keep focus.
Anyway, I am just pointing out that the hard sell on automations is not always net time saved (in fact you might prove to me that in the end, I didnt save anytime bc I took so long to set up an automation) but focus saved and tedium avoided.
