MAREF — GitHub Is Becoming a Giant AI Code Dump

630M repos, half of new code is AI-written, but trust dropped from 77% to 60%. CMU found 6M fake stars. CodeRabbit: AI code has 1.7x more serious issues than human-written. 63% of developers say fixing AI code takes longer than writing from scratch. And the wildest part — AI users are 19% slower but think they're 20% faster. You're getting slower, and you can't feel it.
