Humans need to replicate in order to 'improve', there's no reason that AGI software needs to.
Also, humans do not 'improve' or become more 'intelligent'. They just mutate and change randomly in a randomly changing environment. From a Scientific Materialist perspective, there's no such thing as 'intelligence'. We are bags of random noise, indiscernible from the matter around us.
The entire assumptions around 'intelligence' and 'positive evolution' (i.e. getting better) rely on a 'magical' understanding of the world. Of course, Spirituality gives us a few cues there by most scientific types don't like magical thinking hence the funny paradox of Scientific Materialists running around trying to create something (life) which Scientific Materialism itself denies the existence of as a principle (i.e. universe is matter/energy that works in accordance with a bunch of rules - there's no 'life' there).
