A consideration which I think you should really have in regards to whether you have kids or not is remembering that s-risks are a thing. Personally, I feel very averse to the idea of having children, largely because I feel very uncomfortable about the idea of creating a being that may suffer unimaginably.
There are certainly other things to bare in mind, like the fact that your child may live for billions of years in utopia, but I think that you really have to bare in mind that extremely horrendous outcomes are possible.
It seems to me that the likelihood of s-risks is not very agreed upon, with multiple people who have looked into them considering them of similar likelihood to x-risks, while others consider them far more unlikely. In my opinion the likelihood of s-risks is not negligible and should be a consideration when having children.
Not necessarily
Suicide will not save you from all sources of s-risk and may make some worse. If quantum immortality is true, for example. If resurrection is possible, this then makes things more complicated.
The possibility for extremely large amounts of value should also be considered. If alignment is solved and we can all live in a Utopia, then killing yourself could deprive yourself of billions+ years of happiness.
I would also argue that choosing to stay alive when you know of the risk is different from inflicting the risk on a new being you have created.
With that being said, suicide is a conclusion you could come to. To be completely honest, it is an option I heavily consider. I fear that Lesswrong and the wider alignment community may have underestimated the likelihood of s-risks by a considerable amount.
