Not even, you know that some families aren't so functional and actually very destructive. Children and parents "break up" all the time. Ask anyone who is LGBT for example (especially older and trans).
Also many families have that "one uncle" (or whatever) who is somewhat estranged and isn't invited to stuff.
All without a "super rational techy" view of the world.
Spot on, in my view.
I try to live my life as an empiricist. I didn't choose the family that I was born into. If my family treats me poorly, abuses me, etc., then bailing out on them makes sense.
In the same way, if someone in your life never shows curiosity or empathy towards you, you should probably leave the relationship.
But not a particularly useful observation, just as the concept that "giving to charity is an act of selfishness, since people only only do it to feel better about themselves" might be true but is not useful.
