Terrible agony: Wait for when you have kids.
On the other hand part of me feels sad thinking I will be the "last me". Maybe get genome sequenced/publish books of my face and put it sealed in a landfill somewhere for preservation.
Actually rocks last a long time so probably a statue made with a rock.
Having children changed my outlook on the future quite a bit. First, I feel much more repsonsible and interested in the ecological future, because I intensely love people who will have to deal with the consequences in the future. Second, I hope I will be able to have a natural look into the problems of future generations, when I am old - there is a "strong bond into the future" for me. Third, while I don't feel it's a "future me" that I talk into sleep every evening, it feels like my human legacy. Considering my current reality, my children are probably the biggest impact I can have on the future.
BTW I guess all this is true regardless of genetic bonds.
Many of the points in the article are exactly the kinds of things you want to cultivate with your partner (e.g. self-awareness, good communication, etc) before having kids. If you have a good relationship with your partner, having kids is very manageable.
Our generation is too cynical on kids and it's to their own detriment.
