It is indeed great news on the HIV front. The stem-cell re-boot has long been thought of as the most promising avenue for ridding the body of HIV rather than merely controlling its growth. All I'd say is that this is an extreme and difficult procedure and impractical on any general level - at least right now. But it does suggest that HIV can be gotten rid of entirely if you try hard enough.
I remain in awe of the science and the scientists involved in all of this. Sometimes we really ought to take stock and comprehend the sheer magnitude of the current successes of science. I literally live and breathe because of them.
