Obviously the prerequisite for this would be that backpropogation of error actually occurs in the brain, but what do you think?
Your question uses the language of machine learning to speculate about human memory. That seems pretty thin.
A person barely gets away from a predator or survives a near-drowning. How would erasing that traumatic event have an evolutionary advantage? Your question uses the language of machine learning to speculate about human memory. That seems pretty thin.
I.e Why should I remember a bad ex girlfriend if there was nothing to learn from it?

Depends on the traumatic memory, hence the idea that we've probably optimized for remembering everything rather than the events that have evolutionary advantage. I.e Why should I remember a bad ex girlfriend if there was nothing to learn from it?
Without retention of the memory of trauma, you won’t be forming new experiences.
Amygdala creates emotional responses and utilizes long term memories.
We know from ape studies and amphibian studies that amygdala evolved differently in humans than with other animals.

You remember the bad ex gf because you don’t want repeatability of the trauma. Without retention of the memory of trauma, you won’t be forming new experiences.

Isn't it also arguable that retention of trauma is inherently bad from an evolutionary perspective? Let's say someone retains a traumatic event, gets depressed, ends up committing suicide. In that case, if the brain optimized for survival, it would be beneficial to erase the memory.
I'd argue that the probability of death occurring as a result of severe trauma is greater than the probability of death occurring as a result of forgetting an experience

That's interesting.. so you mean that human memory is not bugged and perfect from an evolutionary perspective?

Retention of traumatic memory is actually an evolutionary edge we have..if you don’t retain that memory, we will keep repeating the same fatal mistake again and again.
I would even go further and look into studies re amygdala and how it works with people who have substance abuse or addiction issues.
Suicidal tendencies have to do with brain chemical imbalances and not necessarily with the formation of long term and short term memory.

Perhaps at this time in history, in some cultures. I doubt our hunter-gather ancestors got depressed and killed themselves after surviving a trauma. I don't think depression and PTSD and suicide happen at constant rates across human cultures, and certainly not in apes or other mammals. You're confusing social pressures and cultural effects with biological evolution.

If a bad ex-girlfriend qualifies as "traumatic" I don't know what to say. The concepts of girlfriends/boyfriends and romantic relationships are cultural artifacts, not products of evolution. Evolution optimizes for mating and reproduction, not individual feelings.
