I am blissfully #childfree, however, if I had kids...
You have no idea what you're talking about. You have no idea what you would do if you had kids, because it's one of the most life altering experiences you can have. All your preconceived notions about what you would and would not do go out the window the moment to strap the kid into the car seat and drive them home wondering why those idiots at the hospital just gave you a baby when you have no idea what you're doing.
While your armchair parenting might be fascinating to you, you seem to forget you grew up in a world with ubiquitous access to pay phones. Where schools were within reasonable walking distance. Where kids would ride their bikes over to their friends' house to see what was going on. Since that era, we got rid of all the pay phones. Middle schools and high schools are now 5 to 12 miles away with limited or no bus service. The majority of social planning happens via group chat.
Good luck coordinating with your kid when their after school club is cancelled and they need to be picked up earlier than expected. Good luck having your teenager stay at home by themselves when no one has a land line anymore and you just carried the only telephone out of the house in your pocket. Good luck having a kid with severe social issues because they're cut off from the other 99% of kids who do have cell phones and coordinate all their social activities through group chat.
