Something I draw from it relates to the discussion that Neo had with Rama-Kandra in the train station. Rama-Kandra gives his position that love and karma are just words: what matters is the connection that the word implies. In a few brief sentences, this seems to cover a crucial difference between the machines and the humans. The machines quantify and structure the terms, and analyze them, while the humans experience them. Some of the rogue programs identify and try to emulate the relationship, while the humans experience the relationship. And, it seems to imply, experience is the means of truly understanding.
How the concept relates to the two dance scenes . . . the fetish club creates a very structured environment, with layers of artifice and props a requirement for participation in the scene. There is nothing simple, spontaneous, or "natural" about the sexual interactions here: it is covered in masks, hidden, not open, covered by layers of latex, leather, and vinyl. (Note -- I am not making any judgements here about fetishists. I am only analyzing how the Wachowski brothers seemed to utilize the trappings of the community for their message in the movie.) In contrast, in Reloaded, we see the joy, the passion for life, and the abandon of the people of Zion as they give themselves over to the dance. We see the simple, down-to-the-skin connection between Neo and Trinity, with no artifice and no barriers: just open love. Even the archway is open -- they have nothing to hide.
It is almost as if the programs are attempting to emulate the environment of the natural humans --- indeed, they utilize the humans inside the Matrix as ornaments and test subjects --- but cannot seem to do so without imposing their structure in the course of reproducing it -- they can't seem to get it quite perfect, as they attempt to study it. (Though this theory kind of goes against the Architect's ability to simulate a perfect virtual environment for humanity, but it turned out not to be perfect, didn't it?) Programs like the Merovingian and Persephone seem to crave human experience -- Persephone in particular, after her bargain for the kiss. Even Rama-Kandra and his wife, two programs, create a daughter. Even the Oracle seems a bit addicted to sensation, as she reiterates again and again how she loves candy, the smell of baking cookies, and other typically human appetites.
Or, conversely, we could view the scene as, despite the repression of the Matrix, the humans will still dance -- their exuberance and vitality can be bound, but not completely controlled. The programs, the Merovingian and Persephone, sat and watched them. Much as they wanted to feel, it seems, perhaps they could not, unless given the feeling by a human. The Merovingian craved the sensation of sex, so he created a situation with the human woman that would produce such a result. Persephone's kiss has already been mentioned -- but it was Neo giving her the kiss. She could only ask for it, it seems: she had to receive it. Can the programs only create an environment that fosters certain outcomes, then, it seems? Can they not duplicate the desired results themselves? Is this another way that at least certain programs need the humans?
I don't know. I'm just musing. Just . . . brainstorming.
I will write more on The Matrix: Revolutions later.
