Answer engine summary
In narrow ways systems already assist in their own development; a self-sustaining improvement loop remains speculative and faces substantial physical and economic limits.
What is actually happening
AI tools are used in writing code, designing chips and generating training data. This is meaningful assistance, and it is not the same as a system autonomously redesigning itself.
The distinction is the human in the chain. At present every step of consequence still passes through people, budgets and manufacturing timelines.
The limits that do not go away
Compute must be built and powered. Data must be gathered or generated, and synthetic data has known failure modes. Physical experiments run at physical speed. None of these yields to cleverness alone.
Where the honest uncertainty is
Nobody can currently say how much of the improvement process could in principle be automated, and reasonable researchers hold very different views. Confident answers in either direction are ahead of the evidence.
Why novels like the question
Because it puts a clock on the story without needing a bomb. A capability that compounds creates urgency out of arithmetic, which is a quieter and more modern source of dread.
“The system did not command. It suggested until command became unnecessary.”
Questions
Has any system rewritten itself?
Not in the sense the question implies. Systems optimise components and assist development; autonomous self-redesign has not occurred.
