While I have it pretty good as programmer, especially in covid times I get lots of calls from clients. I suspect they do so in part because they're going crazy isolating. The pressure to pick up the phone knowing it'll significantly impact my productivity is strong. I think it's a phenomenon similar to the whole 'panopticon' idea: I'm pretty sure not picking up the phone will be fine, but because of the not knowing for sure I still often end up letting the interruption happen. We humans prefer removing uncertainty to an irrational degree, I guess?
