So biological garbage collection pauses then? skip sleep, and the brain tries to run gc cycles during runtime. Causing attention and performance latency spikes. Evolution wrote the original JVM.

Luckily it doesn’t clear all unreferenced memory, though.

Fun fact: Suppressed/hidden/lost memories due to trauma that appear to re-surface through therapy are not a real thing, as previously thought (and still by some psychotherapists). Nowadays it's understood by psychology that any memories "re-surfacing" in therapy are in fact newly created, although the patient themselves cannot tell the difference. Allegedly, whole accusations of childhood abuse may have been created out of thin air, without the victim realizing.

The statement "there is evidence of black swans" does not justify the conclusion "every swan is black".

if you specialize in looking for black swans, and you've looked for more black swans than anybody ever, and all the black swans you thought you'd found have turned out to be sooty white swans, people might be interested in reading about your experience and have their faith shaken that black swans actually exist.

I'm reminded of the story of dragon sightings in Great Britain: after the printing press and newspapers and newspaper reporters chasing stories emerged, as news distribution out from city centers into rural areas increased, it seems dragons picked up and moved farther away, only being spotted in the hinterlands without news.

You apparently would keep your mind open to the idea that dragons don't like the smell of newsprint as no other conclusion could be more plausible sheerly on the basis of logic?

Dragons are smart, and wary of human civilization. They still remember St. George and his ilk.
