Boris Cherny, the "father of Claude Code" at Anthropic, has not written a single line of code for six months, with 100% of the code under his name written by Claude. In February on Lenny's Podcast, Cherny predicted that within a year, the title of "software engineer" will start to disappear, replaced by roles more akin to "builders." Four months later on the Platformer podcast, he predicted that in three years, the number of people writing code and using agents will be 100 times that of today, though they may no longer be called "engineers." Cherny recently shared on X that as functions like engineering, product, design, and data science merge, he sees five types of people on his Claude Code team instead of job titles. Senior engineer Kun Chen, with experience at Meta and Microsoft, replied that roles should evolve with the project, such as prototyper, builder, sweeper, grower, and maintainer. Cherny agreed that roles naturally change with projects and time, stating that the yardstick for measuring developers has shifted from job title to the role played at the moment.
