My father was a major foundation for what I do. Someone has to build these foundations. Many people don't take good enough care of their kids and many responsible people don't want kids. So it is literally world changing to be a good parent.

This! I was constantly looking to grab the next rung up on the career ladder. Having kids made me rethink my priorities on helping them mature into happy, productive members of society. Sure, we made a pile of mistakes along the way in our child rearing efforts. I'm hoping the same, that they will remember me and my wife forever. I think they will.

"I suspect they'll remember me forever"

Laughed out loud at that. Funny because it's so true.

For me personally it didn't stop me from wanting to achieve something in my life. Which I realize only partly overlaps with wanting to change the world. It was impactful nevertheless and I'm sure my kids will remember me :-)

Goes in the other direction also, assuming your own parents are also decent people. You can provide immense satisfaction to them by sharing your time with them.

> I stopped giving a shit about "changing the world" when my kids came into my life.

Does that mean we oldies should be okay with tech employers showing a preference for young workforce?

nah. employers like young people because their desire to "change the world" can be exploited
