Marty Cagan argues that the current trend of cutting managers in favor of pure individual-contributor builders is a temporary phase rather than the future. He restates the principle that experts lead experts: effective leaders of engineers, product managers, and designers must have real expertise in those disciplines. He notes that AI has changed how products are built, pulling many leaders back into hands-on work, but that as building gets cheaper, product and engineering leadership grows more important. He contends that skilled leadership is becoming a competitive advantage, a view he admits could prove wrong.

01Key takeaways

  • Leaders of engineers, designers, and PMs should have real expertise in the discipline they lead.
  • Getting hands-on with new AI tools helps leaders understand how the work has changed.
  • Cutting managers in favor of builders is likely a temporary correction rather than a durable model.
  • As building gets cheaper, decisions about vision, strategy, and outcomes become more valuable, not less.
  • Skilled product and engineering leadership is increasingly a competitive advantage in AI-era product work.

02Key sections

The shift toward builders
Headlines and anecdotes suggest companies are reducing managers and that some leaders are returning to individual contributor roles. Cagan sees this as a necessary but temporary state.
Experts lead experts
Top product companies hold that leaders must be experts in the discipline they lead. Many other companies embrace people-only managers, which Cagan considers a poor model.
How AI changed the work
AI has reshaped how engineers, designers, and PMs work, and many leaders had to get hands-on to understand the new tools. The lower barrier to building has made creation more accessible.
Why leadership still matters
Leaders who spent time in the tools are returning to decisions about vision, strategy, team structure, and outcomes. Some companies that cut managers have begun reversing course.
Leadership as an advantage
As building costs fall, the value of skilled leadership rises, consistent with what he calls the AI productivity paradox. Cagan accepts the risk that this prediction could be wrong.

03From the post

“We are still early in the journey to learn the long-term impact of AI, but one trend that continues to capture attention is that managers and other leaders will be much less important, and that all we really need are skilled individual contributor builders. We’ve all seen the headlines about companies pushing for fewer managers... The post Experts Lead Experts…”
