to answer your Q of what is more cutting edge, one i am for: EMF based approaches, ex think of an MRI that can read and write to the body, and one I am less for is whole body replacement- so there are real companies out there growing clones in a vat with the forebrain knocked out and the engineering problem is how do you get the clone to maturity without it being able to navigate the world to have organs developed enough to replace with your own and some are working towards this with the intent to do a head transplant. for more on this could look up john schloendorn
