Several decades, selective somatic DNA repair is in its infancy and CRISPR is not really a technology that can do it, we don't really have enough of an understanding of the genetic etiology of most diseases (for the most part we just know some promising correlations), and in any case many issues are developmental and repairing the DNA in a grown organism won't fix it.
Between grant proposals, publication abstracts, and popsci translations thereof it's all hype. The PIs don't believe it and neither should you.
