I&#x27;ll give you some engagement. I really think it is sad that you see this as a &#x27;great scientific achievement&#x27; when in actual fact nothing of note has been achieved.<p>The whole article reads like a puff-piece pretending this is a major breakthrough when in fact as far as I can see it not much of note has been achieved, yes, it&#x27;s a mammal but certain types of frogs have been known to be able to freeze and thaw and their neurological systems are working just fine afterwards. In this case all we have is some visual inspection which makes the claim that the brain has been recovered a bit doubtful, it&#x27;s not as if a rabbit using that previously frozen brain is hopping around. (That probably <i>would</i> be a breakthrough.)<p>Cryopreservation, uploading, life extension technology and related fields are for the most quack science taking money from the gullible (or their estates) and spending it on un-productive areas of research. I sincerely wished that HN would stick to discussing things with a bit more solidity, if we afford these subjects the amount of space their proponents would like then HN would go the same way as renewable energy fora that allowed &#x27;zero point energy&#x27; enthusiasts to run unchecked. I&#x27;m happy for you that you wish to live for ever (who doesn&#x27;t?) and that you believe that in your lifetime we&#x27;ll see a major change in this respect but I&#x27;m a bit tougher to convince and I&#x27;ve seen enough bs during my lifetime to solidly vote against giving this stuff more airtime than it already has. Historically, anybody that tried to peddle life eternal turned out to have been lying.<p>FWIW you&#x27;re going to die, get used to it and make the most of the time that you have. If and when the future dictates otherwise you&#x27;ll be able to adjust with grace and on the off chance that it does not you&#x27;ll be happy you followed my advice.
