Yes, listening to those far from death speak about it is akin to listening to the childless go on about childrearing.

- Sure, advice from the inexperienced should be taken with a grain of salt, but that also applies to those with children. The proof of the advice is in the pudding, as they say. The added bonus of raising children is witnessing how the children end up raising their own children and seeing how that worked out for everyone concerned. This rational witnessing of growth and development, in real time and relating to all aspects of life, does reveal truths about human nature that are common to everyone.

- In support of child-rearing advice from the childless, humans do have the advantage of intelligence that makes some experiences unnecessary for understanding. For example, one need not experience a car crash to know that is bad. However, until one bears the responsibity of another’s life and future, what one rationally theorizes about child rearing may not hold up in the long run out there in the world.

but some may ''renegotiate" and some

John Lennon didn't renegotiate the youthful view that was likely designed for publicity. When he was younger Lennon said never trust anyone over 30, and when he was less young he trusted 25 year-old Chapman for a fateful moment.

His youthful comment implies that those under 30 could be trusted, however that implication is debatable as being a mere lawyerly assumption unintended by Lennon.

For example, if Biden says he didn't take one dime from his corrupt family business, this statement does not exclude the taking of millions of dimes.

However, all things considered, Lennon was likely asserting that those under 30 could be trusted, a view that he could have renegotiated in theory, but then he might have ended up hiring an old man to yell at folks to get off his lawn, and he would have been different than historically successful.

Unfortunately for your argument, everyone with children also existed before having children and thus serve as their own control. Ask anyone with adult children if their understanding of child rearing (which is directly proportional to the quality of their advice) was better before or after they actually had kids.
