A space elevator on Ceres (with today's tech) and the gravitational assist of Jupiter for returning payloads back to Earth, could allow us to start mining the asteroid belt costing just $5 billion. (www.universetoday.com)

All deep space mission proposals like this conveniently ignore the unsolved problems of long term radiation exposure and food supply, among many others.

That’s already a solved problem - the billionaires will simply send us up in waves.

Once we're at the technological level of mining asteroids, I think food supply and radiation shielding will be comparatively small challenges. Food can be grown wherever there is sunlight, and radiation can be mitigated by placing sufficient matter on the exterior of the habitats.
