According to the scenario of cosmological artificial selection and artificial cosmogenesis, our universe was created and possibly even fine-tuned by cosmic engineers in another universe. This approach shall be compared to other explanations, and some far-reaching problems of it shall be discussed.

I discuss some of the speculations proposed by Stewart ( 2010a ). These include the following propositions: the cooperation at larger and larger scales, the existence of larger scale processes, the enhancement of the tuning as the universe cycle repeats, the transmission between universes and the motivations to produce a new universe.
