But wolf, how much actual research has been done with embryonic stem cells?
Surely not as much as has been done with adult stem cells, for this very reason. It's easier, more acceptable, and more profitable to research adult stem cells because the government helps with that.

Human flight also showed little promise until the Wright brothers. You should never give up on research, especially research that could do much good, just because it's not showing promise fast enough for you or turning up quite as much gain as you expected. Embryonic stem cell research hasn't gotten nearly as much of a chance as it deserves, because of things like this.
