a16z doubles down on Cognition as Devin now writes 90% of production code

Marc Andreessen announced a16z's second investment in Cognition, maker of coding agent Devin. Key claims: Devin writes over 90% of Cognition's production code (up from 13% a year ago); Mercedes Benz cut an eight-month COBOL migration to eight days; Rivian boosted test generation 10x; and at bank Itau, Devin auto-remediates 70% of security vulnerabilities. Andreessen argues software will now 'eat the world at the speed of compute,' dismissing engineer-job doomerism by pointing to compilers, open source and cloud as prior false alarms.
