Desire is temporary, but the change that desire brought remains forever.
Desire: Banpo-Xism. Permanent: the city.

One "system": reductionist (far too specialised and fragmented). This system: mixing and disturbance between systems. One mode, one sign = one field, one direction → & challenging this... (N >= 2). The basic interaction grammar: finger-skating on mobile... creating their own "field". Skating smoothly with a finger across the grid on the mobile... adjusting the field.

A differential-equation expression
System/output: F
Input (from mobile): f = F' = dF/dt

What does it mean for interaction to be instrumental? The input-output relation generally sits in a different dimension with respect to time. Interaction: the power of the derivative. A change to the system. The power of change, the power of delta. Input provides a temporary flow, a flux, to the system: that is, it provides a rate of change, a delta, a derivative. This derivative, the will of the differential field, affects the whole system.

The same goes from an architectural and urban viewpoint. The city is one system. A total aggregate. The sum of continuous change (F). The terms of this change, the temporary terms of change, are supplied by the acts of building and demolition (differential, F'). And this building, this temporary (time-dependent) building, is done according to the temporary, short-sighted desires of its era. That is, desire (Banpo-Xism, the derivative) is temporary, but the change that desire brought (the city) remains forever.

If input and output are the same, that is at most direct manipulation. Input must be the derivative of output. Multi-mobile interaction: interference between different fields. A multidimensional differential equation. A third-order differential equation. The three-body problem... chaos, emergence.

A → B != B → A
A → B: the castrated sign. A first-order logical error.
B → A: a second-order logical error. The same thing happens with Banpo Xi.
As an A → B → A (negative-)positive reinforcement loop accelerates, it becomes ontologically no different from artificial intelligence. Escaping this is the logic of complex systems: the definition of complexity, the eruption of the real!
A → B: the sign system, minimal marginal difference, Banpo Xi, the consumption of signs.
B → A: the illusion of essence. In the end the same lump of concrete, a castrated essence.
"Acquiring" happiness → making happiness a purpose? A goal? The eruption of the real. The error in which subject and predicate are reversed.

Simulacra: phenomena more real than the real. "The territory no longer precedes the map, nor does it survive it. It is now the map that precedes the territory, the precession of simulacra; it is even the map that engenders the territory" (Baudrillard).
A → B: abstraction
B → A': the formation of the simulacrum (the formation of a castrated original)

The Consumer Society (Baudrillard): we chase only the signs of affluence (Banpo-Xism, location as sign, minimal marginal difference). In the end, a discussion of sign-structuralism. And of what happens when one structure collides with another (collision between fields). These "fields", this canvas: what go stones have been placed on it (on the mobile)? "Signs". H/H/F: happiness, hope and future, the signs and target values of contemporary capitalism. A system of equivalence: fluid, circulating, monetary. But the moment the sign itself becomes the goal, there's big trouble! The moments when A → B becomes B → A...

"Those who have received the miracle of consumption, too, set up an imitation of happiness and its characteristic apparatus of signs, and wait for real happiness to land there" (Baudrillard, The Consumer Society, p. 25).

"Affluence" is the accumulation of the signs of happiness. The illusion of a "dreamland", hope for a future that will not arrive...

Semiotics: in the end, is the city-field I am making a field of signs? And why does the city-field work differentially?
