Create a minimalist and abstract cover image for an article on antinatalism, using contemporary design elements. The image should subtly convey the philosophy's focus on the moral considerations of procreation and the inherent suffering that existence can entail. Imagine a composition dominated by harmonious geometric shapes and a muted color palette, with a deliberate use of negative space to symbolize the absence and void that antinatalism philosophically embraces. Incorporate soft gradients from cool to warm tones, evoking a transition from the calmness of non-existence to the complexity of life, and vice versa, to suggest the contemplative nature of the philosophy. The overall design should evoke a sense of serenity, introspection, and the profound depth of choosing not to participate in the cycle of life. Aim for a cover image that invites the viewer into a space of reflection, encouraging a deeper engagement with the article's themes through its visual subtlety and conceptual depth --v 6.0 --style raw --s 750
