Summary
AI has uneven strengths, excelling in some tasks while struggling in others, creating a “jagged frontier” of abilities. Bottlenecks, or weak points, limit AI’s full automation of complex tasks and slow progress until breakthroughs occur. New advances like Google’s Nano Banana Pro show how solving these bottlenecks can quickly unlock powerful new AI capabilities.

A system is only as functional as its worst components. We call these problems bottlenecks. Some bottlenecks are because the AI is stubbornly subhuman at some tasks. LLM vision systems aren’t good enough at reading medical imaging so they can’t yet replace doctors; LLMs are too helpful when they should push back so they can’t yet replace therapists; hallucinations persist even if they have become rarer which means they can’t yet do tasks where 100% accuracy is required; and so on. If the frontier continues to expand, some of these problems may disappear, but weaknesses are not the only form of bottleneck.
