I generally started by reviewing but after a while (maximum in hours), I just can't keep up and resort to LLMs as sole reviewers.
While the single functions/classes/structs/... can be well though out the code tends to lack cohesion, and especially maintainability. For instance, it never thinks: "I could put this logic in an interface/trait so that if the requirements change I can simply add a concrete implementation that satisfies the new requirements (and potentially use one of these for testing)".
SoTA models can do reasonably good jobs on each ticket, but over time the architecture of the application starts degrading without a human in the loop.
The entropy increases slower with better models but the trend is always towards slop
