Veteran developer warns 11 years of experience "atrophied" by AI assistance

The "Senior-Junior Gap" is reaching a breaking point as AI abstractions begin to replace foundational debugging mental models.

• –Intermittent production bugs still require the methodical hypothesis generation that rapid-fire AI trial-and-error often bypasses.
• –The "GPS effect" suggests a long-term atrophy of the mental "muscle memory" needed to sit with a problem under high uncertainty.
• –Community debate highlights a tension between AI as a higher-level abstraction (like compilers) versus a core cognitive replacement.
• –Serious implications for junior developers: those starting their careers with AI may never build the foundational "gut feeling" required to spot hallucinations or edge cases.
