He is not right person to ask how stem cell affected with age and what we can do about it. I'd quote very prominent stem cell researcher Sean Morrison, who studied this issue in details: “It is not clear whether there is any relationship between stem cell aging and life span”. All claims "fix stem cell and we can live forever" are very much speculative. More of that, almost all discovered genes, affected in aged stem cells, also involved in carcinogenesis. There is a delicate balance between aging, tissue regeneration and cancer. Nobody know so far how to play around it in delicate manner. Therefore your title "Scientist sees aging “cured” by stem cells" is very much misleading and can confuse public. Scientists who are working in the field actually never claimed "aging could be cured by stem cells". I'm studying some aspects of stem cell aging too. Alexey Bersenev, MD, PhD.

Those remaining would become indentured slaves to society.

However, I have to say the predictions in this article sound mostly like hype to me.

If we suspend or inhibit the life/death cycle where will we find the extra resources to support an infinite population on a finite world. Be careful what you wish for a long life in a resource poor decrepit hell, may not be paradise after all.
