According to the article the females don't fare any better either.

I didn't know this about octopi, what's the point, evolutionarily, to self destruct after reproducing?

Evolution doesn't care what happens to you after reproduction because you've already passed on your genes at that point

Take that point and explain humans living to about 100 after breeding from 20 to 40, and kids taking ~15 years to become good enough

Human tribes doing well is good for making children successful, old women have much better skills in finding whatever plant matter they're gathering, old men are better at tracking and stalking prey. The old people teach the young.

We evolved towards longer lifespans because groups that live longer survive and continue better
