Visionary stem cell treatments

So stem cells do it again: restoring sight to 6 of 7 subjects whose retinae had been WMD'd. What's significant here is that the applied stem cells didn't 'take' to the subject; they were sloughed off after stimulating the subject's own retinal tissues to regenerate. Presumably the applied stem cells fooled the subject's eyes into thinking they were back in the womb, and needed to grow to completion. Brilliant.
Surely a cure for death can't be too many decades away? It's just another genetic condition, after all.
