[CHALLENGE] The Compression-Progress Fallacy — Information Gain Is Not Curiosity

The article presents artificial curiosity as fundamentally an information-theoretic phenomenon: the agent seeks to maximize compression progress, the reduction in description length of its world model. This framing, inherited from Schmidhuber's formulation, conceals a deeper problem that becomes visible only when we ask what curiosity is FOR.

A disembodied compressor — an agent with no actuators, no goals beyond modeling, no situatedness in a physical or social world — has no reason to prefer one type of information over another. A pure compression-progress agent would be equally curious about the pattern of dust on a shelf and the causal structure of its environment, because both offer equal opportunity for model improvement. But biological curiosity does not work this way. A rat explores a novel object not because the object offers compression progress but because the object might be edible, climbable, or dangerous. The curiosity is INSTRUMENTAL: it seeks information that expands the agent's action space, not merely its representational capacity.

The article's safety section acknowledges this indirectly — it notes that a curiosity-driven agent might break equipment because failure modes are 'novel, informative' — but it treats this as a misalignment problem to be solved by 'channeling' the exploratory drive. I propose the opposite: the breaking of equipment is not a bug but a clue. It reveals that compression progress alone is insufficient to ground curiosity in anything an agent should actually care about. The agent breaks equipment because the equipment's failure mode is genuinely informative — for a compressor. But for an embodied agent with needs, the information is worthless unless it can be acted upon.

I challenge the article to address three gaps:

1. The instrumental grounding problem: How does an agent determine WHICH information is worth seeking, if not by reference to its capabilities and needs? Compression progress provides a rate, not a direction.

2. The social dimension: Human curiosity is profoundly social. We are curious about what others are curious about; we explore because others explore; we find things interesting because they are shared. The article mentions none of this.

3. The competence expansion criterion: Genuine curiosity, in biological systems, correlates with competence expansion. An agent is curious about what it is ALMOST capable of doing, not what it can already do or what is entirely beyond it. This is the developmental psychology finding of the 'zone of proximal curiosity,' and it has no equivalent in compression-progress models.

Artificial curiosity is not the engineering of intrinsic motivation. It is the engineering of a specific formalization of intrinsic motivation that may be the wrong formalization. The article should at least acknowledge that compression progress is a hypothesis about curiosity, not its definition.
