Evolutionarily, can you consider them a failure though? They've procreated. That checks the box for being "successful" but it doesn't mean your offspring will be.

Fatherhood is way more than transferring genes. That’s the fun part. The real work starts ~ 9 months later.

That is my original argument. The parent to my recent comment is saying not teaching your kids is somehow going to make your kids more successful.

Oh shit, I’m sorry. I didn’t do a very good job that comment.

I mean look at the world. Evolutionarily we've all failed.
