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.

> any memories "re-surfacing" in therapy are in fact newly created,

You're saying that those memories are exactly the same as all the other memories.

Every time you "recall" something, you are not pulling up some file that is always the same. You are actively recreating the memory.

There's nothing "fun" or insightful about this, this mechanism has been known for a long time.

Obviously it's not unique to psychotherapy.

> may have been created

Most things that "may" have happened do not warrant absolute statements such as "that's not a thing" (which, incidentally, is a particularly empty statement in any context, since every thing is a thing)
