There's never been a better time to be a software engineer. The scope of what one person can build has exploded in the last year. Engineers are taking on projects that would have needed entire teams — designing systems, shipping ambitious features, solving problems they previously wouldn't have had the bandwidth to touch. The unlock is cloud agents. The best engineering teams are now running fleets of them: building features end-to-end, remediating security backlogs in an afternoon, compressing year-long migrations into days, fixing production issues without a human writing a line of code. Cognition's own team writes 89% of its code with cloud agents. Scott Wu on how the best engineers are working today and what any developer can do to start building at this scale.
