@pragmatical45,
In the future, we will probably move to extracorporeal reproduction in artificial conditions. For this purpose, one can imagine incubators with artificially grown biological tissue of the uterus, in which the development of the fetus could take place (on a similar principle, one can imagine the artificial cultivation of meat food). Such extracorporeal reproduction may be necessary due to the enlarged braincases of future superhuman species. With a significantly enlarged braincase, natural birth from the mother's womb may be too difficult or even impossible. Of course, it will be possible to use genetic engineering to control the expansion of the braincase. I will also add that the enlargement of the braincase should not be an unlimited or too far-reaching process, the braincase will be significantly larger compared to the current human species, but it will not be a superbrain, with a head the size of a meter or more. Such a limitation results from the possibility of movement of a given superhuman form, from the ability to keep the head on the neck or move the head, etc. Because for the normal development and life of a given intelligent form, whether a superhuman or some cosmic form, sensory stimuli are needed.
Once a species reaches its maximally enlarged head, one can imagine moving on to extracorporeal brain development and creating meter- or multi-meter-long brains in special devices that would be fed and kept alive by this maximally developed species. This would therefore be a hybrid species (two species cooperating with each other).
