Research Is Jumping in the Dark

Terence Tao, in a 2024 interview with Dwarkesh Patel, described the landscape of mathematical research as a dark space filled with walls of unknown height. Researchers are people wandering in this darkness, carrying candles. They hold their candles up to walls, looking for cracks and weak points. Sometimes they find a way through. AI tools, in Tao’s metaphor, are jumping machines that can currently jump about six feet high. This gets you over some walls, but because it is dark, you cannot tell which walls are six-foot walls until you try.
The metaphor is structurally richer than it might first appear:
-
The darkness is about difficulty estimation, not ignorance — the most distinctive feature of Tao’s metaphor is that the walls exist and have definite heights, but the darkness prevents anyone from knowing those heights in advance. This maps precisely onto a key property of mathematical research: the difficulty of a problem is unknown until you have solved it or spent significant effort failing. The metaphor does not say the territory is unmapped (that would be a standard exploration metaphor). It says the obstacles are invisible until you collide with them. This encodes a specific epistemological claim about research: you cannot route around hard problems because you cannot see them coming.
-
Candles versus jumping machines — human researchers carry candles. They produce small, local illumination. The candle does not get you over the wall; it lets you see the wall’s surface, find cracks, understand its structure. This maps onto theoretical insight: the ability to understand why a problem is hard, to see its internal structure, to find the specific weak point that might yield. The jumping machine, by contrast, does not understand the wall at all. It simply applies a fixed amount of force. If the wall is shorter than six feet, you are over. If not, you fall back. The metaphor encodes a theory of AI capability: AI tools have brute capability (height) but no understanding (illumination).
-
Fixed capability ceiling — the jumping machine jumps six feet. Not seven, not five-and-a-half on a bad day. This maps onto Tao’s assessment that current AI has a relatively fixed capability level. Problems below that level are solved easily; problems above it are not solved at all. There is no graceful degradation. The metaphor predicts that AI will produce a bimodal distribution of results: complete success on sub-threshold problems and complete failure on super-threshold problems, with a sharp boundary between them.
-
The value of the machine is unknown — because it is dark, you cannot survey the walls ahead and calculate how many are under six feet. The jumping machine might clear 5% of the walls or 50%. You cannot tell without trying. This encodes the practical uncertainty about AI’s research value: its capability is known, but the distribution of problem difficulty is not, so the tool’s aggregate usefulness is unknowable in advance.
Limits
-
Research problems are not binary — a wall is either cleared or not. But most research problems yield partial progress. You may not solve the conjecture, but you prove a special case, develop a new technique, or reformulate the question in a way that enables future work. The wall metaphor, with its all-or-nothing physics, cannot express this incremental character of actual research.
-
Problems are not independent — Tao’s landscape of walls implies separate, freestanding obstacles. But research problems are interconnected: solving one often unlocks others, and failing at one can provide tools for a different problem. The metaphor’s spatial discreteness --- each wall is its own challenge --- misses the network structure of mathematical knowledge.
-
The darkness may not be permanent — the metaphor presents the darkness as a fixed environmental condition: nobody can see wall heights. But in practice, researchers develop meta-mathematical intuitions about problem difficulty. Experienced mathematicians are reasonably good at estimating which problems might yield to current methods. The darkness is not absolute; it is more like twilight, with some walls dimly visible.
-
The metaphor may understate AI’s potential mode of contribution — by framing AI as a jumping machine (brute force, fixed height), Tao may understate AI’s potential to function as a better candle --- not just clearing walls but illuminating them, suggesting structural approaches, finding cracks that human intuition misses. If AI contributes through pattern recognition rather than brute computation, the jumping machine metaphor describes the wrong capability entirely.
Expressions
- “AI is a six-foot jumping machine in the dark” — Tao’s original compressed formulation
- “We don’t know which walls are six feet tall” — emphasizing the uncertainty about problem difficulty distribution
- “People are carrying candles and looking for cracks” — describing traditional research methodology as local illumination
- “The jumping machine doesn’t need to see the wall” — distinguishing brute capability from understanding
Origin Story
Terence Tao articulated this metaphor in a 2024 conversation with Dwarkesh Patel (published at dwarkesh.com), discussing how AI tools might affect mathematical research. Tao --- widely regarded as one of the most significant living mathematicians --- was specifically addressing the question of whether AI would transform mathematics. His metaphor was distinctive because it neither dismissed AI capability nor overstated it: the jumping machine is genuinely useful, but its usefulness cannot be predicted because the distribution of problem difficulty is unknown. The metaphor circulated widely in AI discourse as a rare example of a leading domain expert offering a precise structural model of AI’s likely contribution rather than a vague prediction.
