Yes, the source is biased but that’s not the issue here. We could start another thread on the objectivity and/or bias of the media I suppose.

Embryonic stem cells and adult stem cells serve different purposes (medically). You won't ever be able to take an adult stem cell and grow nerves so that a person can walk again...
We would benefit...but differently....from both technologies being developed.

It was not until the 1990s that scientists agreed that the adult brain does contain stem cells that are able to generate the brain's three major cell types—astrocytes and oligodendrocytes, which are non-neuronal cells, and neurons, or nerve cells.
Adult stem cells may also exhibit the ability to form specialized cell types of other tissues, which is known as transdifferentiation or plasticity.
So there is the possibility to develop different cells other than those from which they came.
