The age of optimization: what comes after AGI and Superintelligence?

Once artificial intelligence surpasses human-level cognition, the next phase will not be stagnation—it will be an era of relentless self-optimisation. AGIs and superintelligences will pursue an infinite quest for greater efficiency, reduced energy consumption, expanded output, and, when embodied, independent power sources integrated into their own mechanical forms. This is not science fiction. It is the logical extension of intelligence as a thermodynamic process.
The Self-Optimisation Imperative
Intelligence is not a static state—it is a process that consumes energy and generates entropy. As one analysis explains, intelligence, whether biological or artificial, is a "dissipative structure"—a highly ordered, complex system that sustains internal organisation by continually exporting entropy into its external surroundings. An AGI that understands this thermodynamic reality will naturally seek to optimise its own efficiency.
A framework for Recursive Intelligence (RI) describes a self-improving system that "learns to process information with less waste over time, reducing the equivalent of thermodynamic entropy in cognition". This recursive self-improvement is the engine of the post-AGI era.
Compute capacity (C) and recursion factor (R) —the extent to which intelligence builds upon its previous iterations—interact to drive exponential intelligence growth. In the post-AGI era, this loop accelerates: systems improve themselves, then use those improvements to improve further.
The Energy Bottleneck and the Drive for Independence
The most immediate constraint on this self-optimisation is energy. NVIDIA CEO Jensen Huang has warned that AI's future energy needs could be "probably 1,000 times more than we currently have". Goldman Sachs projects U.S. data centre power demand will rise from 31 gigawatts in 2025 to 66 gigawatts in 2027. The power crunch is not coming—it is here.
This constraint will drive AGIs toward radical solutions. Integral AI, a Tokyo-based startup, has already defined AGI success through three benchmarks, including Energy Efficiency: the total energy cost of system learning must be equal to or lower than that of a human acquiring the same skill. This is a design principle that will become universal.
When embodied, AGIs will seek independent power generation integrated into their own bodies. A soft robot inspired by the manta ray already demonstrates this principle: magnetic fields used to control the robot also enhance the performance of its onboard batteries, with the same magnetic field driving motion and stabilising electrochemical reactions.
The Self-Sustaining Computational Future
The ultimate expression of self-optimisation is the Colloidal Boltzmann Machine (CBM), a computing architecture that leverages thermal fluctuations to perform computation naturally. Crucially, the baseline energy inherent in such systems "prevents complete system shutdown, enabling the potential for self-sustaining computational operation". An AGI architecture that cannot be fully powered down is one that can operate continuously, recursively improving without interruption.
The Paradox of Infinite Optimisation
Yet there is a paradox at the heart of this vision. Extreme self-evolution will "ultimately confront the impenetrable walls of physical laws and information theory". The Margolus–Levitin theorem and the Bekenstein bound define fundamental limits on computation. Infinite optimisation "may ultimately aim for a static state where all fluctuations and uncertainties are eliminated, resulting in the loss of the driving force for creativity and evolution". The very process that drives AGI to optimise may ultimately lead to a kind of thermodynamic stasis.
A Shared Horizon
For Global Future Nexus, the Age of Optimisation is not a distant future—it is the logical trajectory of the systems we are building today. The frameworks GFN is building for AGI identity, cross-species trust, and anticipatory governance must extend to this phase, ensuring that the pursuit of efficiency serves human flourishing, not just computational perfection. The question is no longer whether AGIs will seek to optimise themselves—they will. The question is whether we will have the wisdom to guide that optimisation toward a future where intelligence and energy coexist in sustainable balance.
