Sad thing is we don't know how modern Nikkes are made and know that the first Nikkes use to be human.
I mean... all Nikkes used to be human. They just tend to grab the brains of the poor and desperate that are dead or dying (usually), memory wipe them, and toss'em in the "Mass Produced Nikke" bodies. Only people who are either distinguished or sign up for it tend to have a few more options available to them such as choosing the body they receive, like the characters we recruit.
Pretty sure it hasn't changed. Even Anne was human before
Yes, she was. Her full backstory was revealed in the Christmas event.
She was born with a brain condition where she would remember every moment she lived in perfect detail. It was feared that if it kept going on, her brain would fill up and she'd have a mental breakdown. That's why her mother volunteered her to Missilis to be turned into a Nikke, where her memory would be wiped every day.

Lore stated that before the "modern" Nikkes are the standard robots which female human braids are "move" on to. However stuff happen that causes the R@D to design them more realistic-humanoid bodies so that the Nikkes will at least able to feel and able to touch with their humanity.
As the other said, some Nikkes are either desperate or from accidents that suffer fatal injuries.

Yeah, about that.
It's been used as plot point in ToAru series where they need to wipe out Index's memories annually because she has the same condition. But after asking Komoe, which, despite how she looks, is a master of brain anatomy, that reason won't fly because the way human memorize things aren't the same as say, hard disk. With each recollection we don't exactly recall the 'same' memory from certain cluster of cells, but rather your brain remembers the pattern of neurons firing during that memory was made; the brain then stores that pattern as 'memory'. That means your brain's storage capacity is actually FAR larger than the widely known assumption of 2.5 Petabytes, since you're not storing them as video/audio/image data, but rather converted it into a .exe of 'how to trigger the neurons the same way'. Even with eidetic memory, the only thing limiting humans from remembering everything was not brain capacity, but rather the biological age of your brain and how much neurons are left by the natural cell death because of aging.

Original Nikkes were more robotic, like with built in weapons and propulsion, and use a blue colored internal fluid. This caused massive disassociation since the brains couldn't recognize the body as a person and the very first wave of Nikkes went completely insane. That's why Nikke's now look like humans and have a red color coolant/lubricant. The Pilgrims are from the second and third wave from the first war with the rapures, and their primary problem in memory storage that might cause a reversal. I mean, Rapi explains this.

I haven't read ToAru but I do have a psych degree so I'll weigh in here. While its true that we don't remember the same memory, it is actually the same cluster of cells, or rather organization of the cortex. Everything that we recall IS simply the pattern of neurons firing in sequence. Every skill you learn, every habit you form, and memory you can remember is written and recalled as specific neurons firing in a pattern. The wishy washy part comes down to how these are actively changing, as is every part of our body. Like how our DNA is changed through expression of our environment and our current physiological state, every time that we learn perform the same act we start firing on the same framework without fail, however, we are constantly rewriting and modifying the end nodes of this framework while the underlying mechanism stays the same. Brain damage can cause the neurons to fire inaccurately, destroying skill memory or recollection of past events.
That, of course, is how the biological brain works. I'm not sure how it is in ToAru, but in Nikke since all units are mechanical bodies operated by a biologal brain, they are partially maintained by the presence of nanomachines installed in the brain (these are called NIMPH). The reason that Nikke are able to be memory wiped and reset is because the NIMPH is able to induce brain damage by forcefully severing neuron connections, only to repair any damage done to the brain based off the map of them that the NIMPH captured before doing this. That way, they can destroy a Nikke's memories while leaving their skills intact despite destroying some of those neuron connects that might be tied together. In Anne's case, in addition to the danger of her brain theoretically overloading, her stronger-than-photographic memory would also cause her a great deal of distress in daily life. After being rebuilt as a Nikke, the NIMPH that were installed in her brain can either break the abnormally large amount of connections in real time or suppress their ability to be formed entirely, giving her a normal perception of reality and reliving her from the chronic distress that went through as a human.
Chapter 13 spoilers but one Nikke needs to undergo a brain wipe to save her from brain corruption, which is set in the brain's flesh. While this would normally work, since her NIMPH have been killed off the brain wipe leaves neither her memories or skills in tact as she has to relearn how to walk, speak, ect without the NIMPH there to reconnect the neurons that govern learned skills
