What this part means

x is an argument of the function-like quantity on the left; its role is set by that function’s stated inputs.

The passage around this formula

The complexity dimension separates simulation sharply from the other two approaches. A simulation can, in principle, be run at essentially any scale the available compute allows: more grid points, finer time steps, more Monte Carlo samples, larger ensembles. Cost trades directly and continuously against precision. Neither peer review nor formal proof has that kind of dial. A human referee cannot review “80% as carefully” and get an 80%-as-reliable answer in linear proportion; below some threshold of attention, review quality can fail outright rather than gracefully degrading. A formal proof either typechecks or it does not — there is no partial credit inside the kernel, only degrees of how…

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
