I'd like to pull out some stem cells and make a slight alteration to my phi-GULO pseudogene, and inject the altered cells into my liver. That seems relatively simple and within the reach of current technology.
Within 40 years, I can envision sequencing multiple instances of my nuclear DNA, detecting and correcting the transcription error noise, and resequencing what is likely my "original" DNA sequence as the basis for a reconstructed stem cell.
That cell would be multiplied, and the resulting rejuva-goo injected into several points on my body under general anaesthesia.
But that process would still be 10 to 100 times more expensive than one used by people who had access to preserved cells from their younger self. The upside is that this process could also screen for and correct known genetically-linked diseases, or species-wide flaws such as the aforementioned phi-GULO at a marginal additional cost.
