HIV vaccine a reality!

I agree. Though I have no idea of the details, when I look at the progress made in the past quarter of a century, I suspect the techniques for complete cell repair will be perfected soon enough that many alive now will become "immortal". I qualify that, for accidents will continue to happen and over a long enough time, the probability of an accidental death tends to one.

Also, we tend to be killing and sterilizing ourselves anyway through absorption, and consumption of chemicals that inhibit and retard cellular repair, whether it be Tylenol, alcohol, or red dye #3. We identify and pull them as we find the most damaging ones, however I'd venture to guess that there are many compounds that we ingest that combine and breakdown into toxins which result in side effects that we may never fully figure out. I think you are right. Between nanotechnology, and biotechnology we will come up with some pretty amazing things in the next 50 years.
