My thinking was that since I obivously like anyone I decide to have children with and since the child's genes will be a mix of ours and the child is more likley to carry similar memes than a random one it serves my other values to adpot and promote "having children until indefinite lifespans or cryorevival are available" as a value.

However my adopting "having children" as a value hasn't yet resulted in me having any children.

Unfortunately I have a feeling that the loss of ability to consistently use contraception is much more robust than a positive desire to not use it when optimal, evolutionary speaking and that in the long run we can't really run away from this as long as agents keep replicating.
