Chamath Palihapitiya posted that 99 percent of code remains human-written and sloppy while agentic code avoids those mistakes, so replacing it would lower error rates and security incidents. Ross Wightman replied that agent-written code introduces its own errors and can turn out net worse without close developer oversight. Gergely Orosz called the original claim bold and said agentic code stays as buggy as its training data while adding harder-to-spot vulnerabilities. The posts contain no independent confirmation of either side's predictions.
