“For every 400 LOC written by a LLM Coding Assistants (at best, less for code that are hard to review), we need one professional senior developer to spend 1h of his time reviewing the code.”
The standard defense of AI coding is that a human reviews the output. Depierre does the arithmetic and the defense collapses. Senior review time is the scarcest resource on any team, and generating code faster than it can be reviewed just moves the bottleneck somewhere more expensive.
