Weak links
A weak link is an essential task or input whose poor performance constrains an otherwise productive system.
Explanation
Many production processes work like chains: their parts complement one another and cannot easily be substituted. Faster software, better machines, or more capable AI therefore create limited value when one necessary step is still slow or difficult.
For AI, weak links help explain why rapid progress in model capabilities may translate into slower economic growth. Human judgment, physical work, data, regulation, or organizational change can remain bottlenecks even after many cognitive tasks become cheap to automate.
