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.

Gonna need some citations on that “fun fact”

That is extremely weak to nonexistent counter-evidence that seems to focus on supporting Loftus, who has put a lot of effort into the defense of her public persona. I don’t disagree that it is possible to manufacture memories but the evidence isn’t there to support your conclusion or the converse.

Recovered-memory therapy (the topic of the Wikipedia article) is very clearly quack science and has been discredited.

Some of the techniques used in the therapy include giving patients sedative-hypnotic drugs to put the patient in a waking dream-like state while the therapist asks leading questions to get them to "remember" an event. The same drugs they used are known to be associated with false memories, like when someone falsely recalls something from a vivid dream as having actually happened.

It has fallen out of favor based on a lack of evidential support, for sure. It has not really been dismantled publicly scientifically, but mostly quietly, perhaps in order to protect its practitioners, perhaps because the research cannot currently be ethically conducted.

I am not advocating for it, just stating the near total lack of substantive scientific evidence presented either in support or opposed.
