Aging brains blend memories together instead of just forgetting them(studyfinds.com)

This I belive, I used to have intimate knowledge of my niche internet lore and keep learning I am blending years around.

I can't wait to tell my dad about this study. We recently got into a heated debate when he insisted that I was a toddler on a family vacation we were reminiscing about, when in fact I was a teenager on that particular vacation, and he was mashing it together with memories of a different vacation. He is 75 but is in pretty good cognitive health, no signs of dementia besides this unreliable long term memory.

As a person who used to be a super genius then turned 40 and is now only a regular genius aging has been very hard to get used to.

Don’t worry. By 60 you’ll remember being a super genius again — with increasingly convincing evidence.

I think at 60 the definition for super genius just changes to "having regular poops".

It's interesting to compare and contrast LLMs and biological brains. Both use a form of "compaction".

Compaction is not even an intrinsic function of an LLM, but of it's harness or whatever code is calling it. When an LLM compacts something it's just creating a summary of the previous conversation using the same mechanism that it uses to generate any other text. It doesn't "forget" the text from before the summary, it just no longer receives it when it is invoked.

In contrast, when we forget something we are not summarizing anything, we are just losing the ability to recall something. We might remember what we have forgotten later on, showing that it is still somewhere in the mind, and that the reason we have forgotten it is not necessarily because it has been discarded.

Even then, what this article is talking about is not even normal forgetting as a function of the brain. It's talking about a degenerative and dysfunctional form of memory loss where different memories are confused with each other.

That's largely because we intentionally model llm "brains" after the human brain.

Things seen at a distance blend together, as opposed to just disappearing.

So that's an interesting parallel. Says something about memory.

FYI this is LLM slop. Consider the information to be entirely unfounded.

What, the paper from Mekbib and McDonough, or the divulgation from Antonaros?

Supposing it is the submitted (under Antonaros), see https://news.ycombinator.com/item?id=49538906

Nothing further from the truth.

Ignore my account if you wish. The handling of memories as the corruption through conflation and obfuscation of the original is widely accountable.

The part of the holographic memory is unexplored for obvious reasons (beyond modern scientific reach.) Many individuals extraordinary behaviors may be explained by the lack of neurological access by others, not information storage availability.
