"To medical professionals her condition looks a lot like dementia — amnesia is a common symptom of dementia — but she doesn’t have dementia. One difference is that (as I understand it) dementia is a progressive disease, while this amnesia is stable."
Dementia is a multi-system failure, memory + CPU. Amnesia, on its own, is a failure of memory, the CPU is working fine. Medical amateurs, like tech amateurs, may be confused by the difference. Tech professionals, like medical professionals, ought not to be.
Since we do not yet have the capability to switch out human memory 'cards', making use of the CPU to compensate for the faulty memory card is a great hack.
There is a reason I check out Hacker News on an almost daily basis. This is it.
