alt Hacker NewsNeeding an app or tech device to announce to your spouse and children at home that dinner is ready is beyond antisocial, actually. It's ridiculously sad and pathetic.
And then people will complain that children these days spend their time in front of a screen...
I think @prmoustache is also referring to manners in general.
Maybe you live in a smaller space than I'm imagining, but if Dad's in the kitchen making dinner and other Dad is in the garage trying to figure out what he's going to need for the backpacking trip next weekend and the youngest kid is in the office with her headphones in listening to music while doing her homework and the eldest is upstairs chatting with his friends on Discord, then the options are
A) scramble around the entire house going "dinner in 5 minutes"
B) yell the same, hope people hear it, and negatively affect your mood
C) have some sort of system that lets everyone know with the tap of a button.
