The bottleneck in software development has shifted from keystroke velocity to cognitive load. AI autocomplete and code generation make syntax production trivial, but architects still need to hold mental models of complex systems to make safe changes without cascading failures. Competitive advantage now accrues upstream to system design literacy and downstream to testing infrastructure, not to developers who can type faster with a copilot.
