It's like a buffered queue, if the producer (AI) is too fast for the consumer (dev's brain) then the producer needs to block/stop/slow down other wise data will be lost (in this analogy the data loss is the consumer no longer having a clear understanding of what the code is doing)
One day, when AI becomes reliable (which is still a while off because AI doesn't yet understand what it's doing) then the AI will replace the consumer (IMO).
FTR - AI is still at the "text matches another pattern of text" stage, and not the "understand what concepts are being conveyed" stage, as demonstrated by AI's failure to do basic arithmetic
