My business partner sent a 5K vibe-coded PR that he didn't even test

A developer's business partner used AI to rapidly code a 5,000-line payments backend module without testing it or collaborating, resulting in a non-functional PR with untested endpoints and incomplete documentation. The frustrated developer views this as symptomatic of a broader problem: developers outsourcing their cognitive work to AI tools and losing their technical skills in the process, ultimately delivering poor-quality code.
