I am. However, there are times where I feel a slight guilt not responding right away and I still catch myself reaching for my phone thinking there has to be some notifications to check.
If I could ask for one thing, it’d be an easier way to toggle Silence Unknown Callers (which is in the anti-spam category, not quite what the article is focused on).
I’m old enough to have been a heavy AIM user back in the day. I don’t want to toggle on/off my “readiness for chat”, nor do I want to consider my recipient’s readiness for chat (aside from time of day sensitivity). I prefer today’s tools that put the onus on the recipient to configure their notifications suitably (hint: if in doubt, just turn the notifications off, and poll manually on an appropriate longish interval). If a human complains about your slowness to respond, that’s a social norms problem, not a problem with the tools.
