Hosts Phil Bowermaster and Stephen Gordon discuss the limitations that can most seriously impact the future:
Resources -- We've been warned about these limits many times.
Capability -- Do we have what it takes?
Lifespan -- Will we live to see it?
People -- Well there's no shortage of those, anyway. (Or is there?)
Ideas -- Let's not run out of the Ulitmate Resource.
Freedom -- What if we have it all except for the ability to choose?
Will -- What if we just stop caring?
Are limitations something we ened to accept or to overcome? Which of these is most likely to impede our progress?
