I've been pricing my current business venture. I reckon everyone who's gone into the resurrection business has got it wrong so far.
What all the cryonics companies seem to offer at the moment is the storage of either a body or a brain at liquid nitrogen temperature until such time as it can be resurrected through scientific advances. The idea is that the storage firm eventually hands the stored meat to a future equivalent of a hospital and gets it re-grown in a rejuvenating fashion which will allow the revenant to age its way through another lifetime and then die again. I fail to be convinced. The idea that this frozen wetware can be re-attached to nerves, if necessary, and then sparked back into a functional state so that it can walk around chatting, having presumably lost a lifetime's wear and tear, is a bit far-fetched.
If, on the other hand, you assume that all the laid-down memory of a person is set into the physical structure of the brain - a reasonable assumption - then all you need do is preserve the entirety of that physical structure. It can, when technology allows, be scanned at a high-enough resolution to act as data in a computer simulator. The simulator has the potential to improve greatly on a person's current capacity to recall events. Speaking for myself, I know there's information at the back of my mind which it takes me minutes or hours to dredge back to a conscious level. If it's there, and the simulator is adequate, the lapse disappears.
I reckon all of that connexional information can be stored if the brain is simply pickled with sufficient care. So long as no bacteriological or parasite infestation can survive then the brain will remain undegraded in permanent stasis. We can test this notion because there are brains in museums which have been kept in formaldehyde or ethanol for over a hundred years and still have all the microscopic neurons intact and ready for inspection.
$300 per tonne, formaldehyde, and no subsequent maintenance. No annual charge for topping up the liquid nitrogen. Admittedly you're not going to regain consciousness within the same biological substrate, you'll be a dataset in someone's computer, but you'll be a lot more robust. Unlike your current manifestation you'll have indefinite survival and faster recall, improved peripherals and guaranteed human rights respected under the terms of the contract.
I can offer 999 year leasehold storage, including one complete ResurrectionScan™, at £2,000 for extracted brains delivered to our storage facility. This modest price includes one preservation kit and postage carton to be supplied to the undertaker or private hospital of your choice. Alternatively you are welcome to check into our dismantling crematorium hotel prior to death, where our technicians will ensure brain removal according to our own exacting standard. Hotel and cremation fees are payable in advance and additional to the preservation charge.
