When AI writes 100K lines of code, QA becomes the whole job

Artur Balabanskyy, founder of AI-first agency Tapforce, argues that AI code generation hasn't eliminated the core challenge of software development — it's just moved the bottleneck from writing code to validating it. When AI can produce 100,000 lines of code in hours, QA becomes the critical discipline. Drawing on his journey from building an AI grandma with if-else statements at age 13 to running a multi-million dollar agency, he contends that developer roles are shifting from builders to system supervisors. He advises developers to treat AI as a coding partner, focus on product and UX skills, and build constantly — because writing code is no longer the hard part; deciding what to build and making it useful is.
