Agreed, though whether we have time for this to happen seems doubtful. It would require a dramatic slowdown of faux-growth to enable natural systems to recover, while we spend the time needed (probably centuries) to develop tech with sustainability approaching that of evolved systems. There's no a priori technical reason why this should not be possible, but political realities make it hard to imagine. Maybe another 'intelligent' species can make this happen in a few millennia.
