If you care about having children, why not do both?

I think the resources spent on cryonically preserving yourself would be better spent on other things. Yes, one of those things is "having children and raising them properly", but it seems likely that one would soon see diminishing returns if one 'overinvested' in one's children. Happily, there are plenty of other worthy causes to take up the slack e.g. donating money to charity, building a garden shed, putting extra insulation in your loft, etc.

Actually, I think cryonically preserving yourself has negative value unless there's some way in which you will be 'interesting' or 'useful' to future generations. For some people this will be true, but not very many.

I think that if people could somehow 'stand back' from their own biased perspective on the world, they would realize that there isn't anything preferable about "one of the people in the far future having distant memories of being me" as opposed to "no-one in the far future having such memories."

That's not nearly true.

Aye. I wasn't thinking when I wrote that bit, so as you can see, I've edited my original comment.
