Same honestly. But here's my take/speculation.
What we know (assuming the person who got deleted by the assembler was speaking the truth):
This society has achieved "immortality" by uploading a human's conscience to the Paradise System via a chip, to outlive a mortal body. After death, this conscience is placed in an artificial (?) body (Why not do so from the start? The artificial body still seems to be mortal/somewhat biological in nature?) to experience "paradise". This paradise, as it turns out, really is just an exploitative system designed to keep one working even after death, with the false promise of an even "better" life at a higher level.
Interestingly, both assemblers don't seem to have ever recognized a person from before their death.
The Question:
To me, the biggest question is whether a life prior to the system truly exists. Since conscience data can be manipulated (as seen when introducing the artificial illness to keep you stuck at level 2), memories prior to death could just be fabricated entirely. This would also explain why they can't recognize anyone from before their death (another explanation could be that the conscience is simply altered too extensively).
On the other hand, people don't seem to reproduce in the Paradise System. Why go to the trouble of dealing with mortality and "resurrecting" people after their death instead of creating artificial life to begin with?
Why allow new inhabitants into the Paradise, when resources are apparently limited?
Here's my conclusions from this:
I think it makes sense to have Paradise's inhabitants work, as the system needs to sustain itself somehow.
Existence seems to be fundamentally coupled to data, more specifically, the conscience data collected via the chip. This data is prone to both degradation (over time and due to damage to the chip/death) as well as manipulation.
This Paradise System is bound to produce
massive amounts of data, which need processing and storing. This is where I assume the third level comes into play, reducing former paradise inhabitants to living (?) computers/datacenters.
Speaking of computers/datacenters: The woman who gets deleted mentions calculations multiple times. It seems highly likely the people on the second level are performing calculations for some purpose as well. Level one? The people who built the Paradise System?
Which brings us to the second key aspect, degradation: Degraded consciousnesses can't fulfill their purpose on the second level anymore, leading to banishment to the third level, presumably performing simpler tasks/calculations. This also has the nice side effect of stopping the population from growing infinitely.
If you're a bit interested in informatics, you'll eventually discover that randomness is a very tricky thing to achieve with computers. This is where I assume mortals come into play: You need humans outside the Paradise System to generate fresh data. This is also why you can't have people reproduce inside the Paradise System: You would basically create a cesspool of degraded data...
Thus you end up with
creating a cycle of fresh data that's harnessed for processing power until it eventually gets discarded after exceeding certain degradation levels.
My interpretation
Maybe that's just me, but I think this is oddly reminiscent of the current AI situation we're in:
Training AI on its own data leads to degradation (apparently, there's a term for it called
model collapse). Our (current) understanding is essentially: more data = better model. At the same time, the data needs to be of high quality, and this is where humans come into play: Feeding vast amounts of human-generated data into all kinds of AI models.
So even though there's a future where AI (or in the case of the oneshot, the Paradise inhabitants) might seemingly make humans obsolete, they'll be harvested for fresh data to keep the system from falling apart.
And maybe the woman getting deleted is representing one of the people working on AI falling prey to their own creation...
Sorry for the rant lmao
