The financial ecosystem is made up of agents and interactions in an open system that generates, second to second, thousands of interactions between human, non-human, and exobiological agents. As financial systems are part of social complexity and as a result of increasing technological transformation, this thesis refers to a transdisciplinary way of thinking that helps to answer questions about the ecosystem evolution of and to seek answers in the collective wisdom of a group of sciences and not in selfishness and the absolute truths of disciplinarily. This thesis turns to complex systems, network science, computer science, evolutionary biology, topology, geometry, history, economics, sociology, and fiction to identify possible futures that the financial ecosystem has by incorporating technological transformations, symbiosis with the technological ecosystem, and the synapse of natural and artificial intelligence. It is to understand the emergence of a computational ecosystem because of symbiogenesis and unknown computational life. But also, of a scientific fusion because, with the articulation of several sciences, it is possible to simulate interactions that are not visible on the human scale, since with the synapse of both intelligence will be easy to interact in micro-times and micro-spaces, reducing temporal and spatial differences that have accompanied us. What is the future of financial agents? How will be the interaction between those agents? Why will technological transformations and convergences change the ecosystem? In the following pages, we will learn about the evolution of financial agents from the historical perspective until the computational simulation of the ecosystem's possible futures. In consequence, I articulated historical sources, mathematical models, sociological and philosophical arguments, physics theories, scripts, simulations, computational code, and imagination to identify the global emergence of the computational financial ecosystem. In this ecosystem, the digital agglomerations will be the form of interacting between human, non-human, and exobiological agents, but also to co-evolving towards new ways of interacting in Gaia, a new Gaia. The reader must be prepared to learn from the mechanisms that identify financial agents, from the ecosystem dynamics, from processes of transmission, diffusion, and transition of technology, from the ecosystems symbiosis, from the synapse of both intelligence and the symbiogenesis of a new type of financial agents, always in the network science framework. Because the agents will move interchangeably in the ecosystem, and understanding the distance between them will be fundamental. Also, to alternate in different temporal and spatial dimensions because as an open system, this thesis explores your curiosity, and if you want to deepen a fact or a specific narration, you must leave it or look inside the paths that lead you to find the answers.
