What it does explain is the outcomes of events chosen at random - eg
our birth moment, or the beginning of the universe. These are
relatively simple. It does predict that complex moments (eg our
present minds or the present state of the universe), are unlikely to
appear out of nowhere. They are far more likely to appear as a result
of some evolutionary process that delivers the complex moment from
some simple moment.

This, I believe, succinctly sums up the debate on the ASSA vs the
RSSA we had earlier.
