Positives

Implementing a 'self-review' flow could enhance accountability and set clearer expectations for code quality, especially with AI-generated contributions.
AI-assisted coding tools can significantly speed up feature delivery, although the review process currently hampers this advantage.

Concerns

Mandatory senior reviews of AI-assisted code may not improve code quality, as they require significant time and may not catch all issues.
The review process for AI-generated code creates a bottleneck, negating many of the efficiency benefits that AI is supposed to provide.
Engineers feel that the current system prioritizes superficial metrics over genuine quality, making it difficult to navigate career advancement.
