This argument is not very strong: is "physical strength" some abstract, platonic thing divorced from reality? Does a person's bench press, squat, deadlift, and overhead press capabilities have nothing to do with strength? Or instead, is there some underlying latent capability we call 'strength,' that is correlated with performance in a broad but constrained range of real-world tasks that humans encounter and solve, whose value is something we'd like to assess and, ideally, build machines that can surpass?
