I have been remote for 11 years now and have two children 9 and 12. I can't imagine what it would have been like if I had spent the week out commuting between the hours of 7am to 7pm, we would have lost out on so much bonding time with their daddy being an integral part of their life. I managed to be highly productive, build a career, yet be there for bath times, tucking into bed, school plays / sports days, nursing…
I can't imagine what it would have been like if I had spent the week out commuting between the hours of 7am to 7pm FWIW, I commuted through most of my son's childhood. I still made it home for those things you list. But, it did take optimizing house location/commute, etc. I certainly wasn't gone 7am-7pm. Even with 60 min of driving and 60 min for lunch, that's an 10 hour day.
To spell the quiet part out loud here, what you're describing is an extreme privilege in a world where homes near tech campuses often go for $1M+. New fathers aren't going to have a down payment for even $600k+. Tech at this point starts as a rich persons game which is why so many tech workers intermarry with other wealthy people. It takes two or a trust fund to do what you're talking about early on, unless you want to rent in a place where rents are highly inflated. At that point, you're choosing between a family and any shade of financial freedom.
