Sorry, to avoid embarrassment I didn't include the conclusion:
Since, as stated, non-carbon chemistry is limited, non-carbon life (very broadly defined as replication of information) is either impossible or incredibly boring.
but this is what I’m saying. perhaps it’s possible to have life from other elements, but carbon-based life simply dominates it to a degree that it doesn’t survive
