AI will eliminate the tedious 'hazing' phase of a junior developer's career. Instead of spending years on boilerplate code and simple bug fixes, new engineers will enter an 'officer's school,' immediately focusing on high-level strategic tasks like system architecture and complex problem-solving.

As AI coding agents generate vast amounts of code, the most tedious part of a developer's job shifts from writing code to reviewing it. This creates a new product opportunity: building tools that help developers validate and build confidence in AI-written code, making the review process less of a chore.

AI tools are automating code generation, reducing the time developers spend writing it. Consequently, the primary skill shifts to carefully reviewing and verifying the AI-generated code for correctness and security. This means a developer's time is now spent more on review and architecture than on implementation.

Senior lawyers use AI for a quick first pass, but their deep experience allows them to instantly spot inaccuracies or weaknesses in the output. This accelerates their high-level strategic work, providing a greater productivity boost than what junior lawyers get from automating basic tasks.

Simply deploying AI to write code faster doesn't increase end-to-end velocity. It creates a new bottleneck where human engineers are overwhelmed with reviewing a flood of AI-generated code. To truly benefit, companies must also automate verification and validation processes.

AI coding assistants won't make fundamental skills obsolete. Instead, they act as a force multiplier that separates engineers. Great engineers use AI to become exceptional by augmenting their deep understanding, while mediocre engineers who rely on it blindly will fall further behind.

While AI coding assistants appear to boost output, they introduce a "rework tax." A Stanford study found AI-generated code leads to significant downstream refactoring. A team might ship 40% more code, but if half of that increase is just fixing last week's AI-generated "slop," the real productivity gain is much lower than headlines suggest.

Experience alone no longer determines engineering productivity. An engineer's value is now a function of their experience plus their fluency with AI tools. Experienced coders who haven't adapted are now less valuable than AI-native recent graduates, who are in high demand.

Data on AI tool adoption among engineers is conflicting. One A/B test showed that the highest-performing senior engineers gained the biggest productivity boost. However, other companies report that opinionated senior engineers are the most resistant to using AI tools, viewing their output as subpar.
