I struggle with calling this dystopian, even though I partially agree. I think it's great that we push work-life balance, and I believe we should disconnect but I can see where these advertisements might be comforting to some.
Back in the 70's my dad worked in an office and wasn't home until 7:30. He only made it to a handful of sporting events and school events. If you asked him, in the 70's, would he prefer to be in the office making that phone call or be sitting at <insert kid's> <insert event> he would choose the latter without hesitation.
For a more recent example, my sister is in sales and will get phone calls any hour of the day. For her, being able to go out and do things with the occasional 5 minute interruption is an absolute game-changer. Not just answer phone calls, but to bring up the customer information and maybe write a quick email.
