Quoting luminousmen: Senior Engineer Fatigue

An article I related to a lot on seniority and what it brings to the table (even though the term fatigue gives it too much of a negative connotation IMHO):

Senior Fatigue is characterized not by a decline in productivity but by a deliberate deceleration. The vibrant energy of younger engineers, bursting with rapid pull requests and overflowing with design documents, starts to give way to a more measured pace. At this stage, seniors might send fewer pull requests or be quieter in meetings, but this isn't an indicator of lost productivity. Quite the opposite — seniors are often finding more efficient, impactful ways to contribute, leveraging their vast experience.

The seasoned engineer learns that sometimes the best code is the code you never wrote. They become adept at delegating tasks, capitalizing on the strengths of their colleagues, and asking the dreaded question, "But why?" — a question that often leads to the heart of what needs to be solved, avoiding unnecessary work and focusing on what truly adds value.
