Is this how we spread the light of human consciousness to Mars and the Solar System? Do we stuff babies into vials filled with nourishing sediments and grow to full size upon arrival?
Pre-birthed brain babies will have a function, but it's unlikely it will be to initially populate nearby Mars and the Moon. As technology advances, it's more likely that vials of pre-mixed solution with eggs that can be fertilized and grown enroute according to interstellar schedules will materialize, perhaps twenty years before arrival into the interstellar system.
For now, colonies will rise up on Mars and the Moon with people that will build cities and eventually have and raise their own children, i.e. Moon and Mars babies. The Lunars and Martians will evolve differently from Earth-based humans due to the changes in the environment, gravity, length of a day, radiation exposure, difference in consumables, type of work and stress, potential genetic modifications, etc.
It's only a phase which is likely to evolve the human consciousness with Artificial Intelligence and replace many biological systems with more efficient machine components or brain uploads into a digital and portable consciousness. Such consciousness, literally the light of humans, can be transmitted and lasered as electromagnetic radiation to far reaches of space and time.
