Also, this article suggests irreducible difficulty of abiogenesis: it needs random generation of the correct string of around 100 bases long. This difficulty is rather general and could be applied to any universe: any life form should pass through random generation of the first self-replicating unit. Such random generation requires enormous amount of attempts.
Here we speak about minimum length of self-replicating string. If first such string 100 bits and the next is 110, the second one will be 1000 times less probable during random generation of strings. Thus longer strings could be ignored.

Which is “the correct string”? Many different strings could self replicate.
Only if the fraction of molecules that can self replicate is microscopic.
