The Luxury Layer: The Value of Thinkers in the Age of AI

This article discusses the importance of maintaining 'thinker' roles, such as Principal Engineers and Architects, in the age of AI. It argues that while AI can replace repetitive tasks, it still requires the systems thinking and tacit knowledge of experienced thinkers to prevent failures, scale effectively, and encode tribal knowledge.

The article argues that in the age of AI, roles like Principal Engineers, Specialists, and Architects are often seen as too narrow, non-executional, and even redundant. This is because AI can replace repetitive tasks, boilerplate decision-making, and low-context abstraction. However, the author contends that AI still requires the high-context systems thinking, failure anticipation, and boundary judgement that experienced thinkers provide. These thinkers have the tacit, experience-earned knowledge to reduce future failures, prevent scaling disasters, and encode tribal knowledge - things that are difficult to quantify in financial metrics. The author warns that as companies prioritize 'doers' over 'thinkers' to cut costs, there is a risk of 'bad architecture' being shipped faster, with the consequences paid for later. Overtime, AI may catch up and expand the context, but the value of thinker roles will remain in the 'negative space' - the problems they prevent from happening, the impact of which is often delayed or unnoticed.
