Fidelity Is Not World Modeling: Why Generative Video Is a Weak Proxy for Usable Internal State
Photorealistic future-frame generation is routinely accepted as evidence of world modeling, but visual plausibility is uncorrelated with controllability and intervention consistency; teams that adopt fidelity as their acceptance metric will ship systems that fail exactly the planning tasks the spatial layer was supposed to unlock.
AngleTake the strongest pro-generative-video claim at face value, then specify the failure modes (counterfactual queries, intervention response, novel viewpoints) and the evaluation harnesses that would expose them.

The ImageNet ordering — corpus and benchmark before architecture — is the correct sequencing for 3D scenes and physical interaction traces, so budget and headcount should shift toward data pipelines, labeling taxonomies, and evaluation suites before model work is staffed.
AngleArgue against the prestige ordering that treats architecture as the primary research bottleneck, and translate the corpus-first principle into concrete team-shape and budget consequences.

Treating spatial intelligence as one monolithic 'understand 3D' capability produces unattributable failures; separating generation, forward prediction, and decision layers with distinct interfaces makes failures localizable, vendors substitutable, and latency budgets assignable per function.
AngleConvert a three-word capability list into an architectural contract: what each subsystem owns, what crosses its boundary, and which subsystem can be replaced by a non-neural component.

Capital concentration on one scientific bet can substitute for headcount scaling up to a point, but concentrating a frontier bet in a small team with no redundancy moves the risk from coordination overhead to single-thesis failure, and the article identifies which resources are actually binding before either model should be copied.
AngleSteelman both the small-team leverage claim and the giant-competitor risk, then specify the conditions under which the concentrated model is a defensible strategy rather than survivorship bias.
