Can you guarantee that it will be a potential cure in 15 years? I have an illness. It has been "cured" several times using various drugs. People keep saying the cure is around the corner... "oh by next year," "in three years," "in five years," "in six months." People have been saying that for two decades now. Everyday there is new progress; some people show results, some haven't. Animals are tested on. Been 5 years now since I got hit with the news, and so far none of the predictions came true yet.
You see, the difference between someone that want CIs and someone that want stem-cells is that the stem-cell folks are "technology will be better tomorrow" while the CI folks are more like "live life; have a fun one."
Dumb comment to make on a Deaf-centric forum.
