  Found 328 claims (584.3s).
    Categories: definitional=16, empirical=41, logical=235, structural=36
    Formal (Z3-encodable): 205
    C1: If AI displaces human workers faster than the economy can reabsorb them,
it risks eroding the very c
    C2: Knowing that AI displacement erodes consumer demand is not sufficient 
for firms to stop it.
    C3: In a competitive task-based model, demand externalities trap rational 
firms in an automation arms ra
    C4: The resulting loss from over-automation harms both workers and firm 
owners.
    C5: More competition and better AI amplify the excess automation beyond what
is collectively optimal.

Step 2b: Extracting formal model structure
  Formal model: 10 assumptions, 18 propositions, 6 equations, 7 policies 
(101.1s)
    P1: In a competitive task-based model, demand externalities trap rational 
firms in an automation arms ra

strategy that exceeds the coope

monopolist fully internalizes the ex

in which every firm displaces

Step 3: Analysing claims (contradictions, key terms, attack angles)

that over the past four decades the offsetti

  Key terms: 76
    AI labor displacement, task-based model, competitive task-based model, 
demand externality, automation externality, automation arms race,

  Attack angles: 8
    - Model realism and dependence on restrictive assumptions: Argue that the 
main result may be an artifact of a highly stylized setup: one sector, one 
period, sy
    - Welfare accounting may ignore real productivity gains: Challenge the claim
that better AI worsens distortion without improving the efficient benchmark. The
