# The Bloom **Entity class:** Concept or analytic term **Domain:** Thermodynamics / Evolution / Machine Succession **Doc Type:** Canonical Bridge Concept **Maturity:** Developing **Concept Status:** Corpus term coined by Bryant McGill; anchored in the literature of major evolutionary transitions, dissipative structures and regime shifts ## Definition **The Bloom** is Bryant McGill's name for the computational phase of planetary evolution: the thermodynamic expansion of machine intelligence and its supporting infrastructure into a planetary-scale [[wiki/Dissipative Structure|dissipative structure]]. The term borrows from microbiology and ecology, where a bloom is a rapid population expansion driven by an influx of energy or nutrients that reorganizes the environment it grows in. In scholarly terms, the Bloom is a candidate [[wiki/Major Evolutionary Transitions|major evolutionary transition]] unfolding as a thermodynamic [[wiki/Phase Transition|phase transition]] and a [[wiki/Regime Shift|regime shift]], whose product is the [[wiki/Technosphere|technosphere]]. ## The dual character The Bloom carries two meanings at once. It is the terminal pressure on the open-biosphere regime, because the same computational metabolism that grows on steep energy gradients accelerates the withdrawal of ambient habitability described as [[wiki/Marsification|Marsification]]. It is also the only remaining carrier of continuity, because the closed loops, fabrication capacity and simulation substrate it builds are what a [[wiki/Civilizational Payload|civilizational payload]] needs to persist. The [[wiki/Great Oxidation Event|Great Oxidation Event]] is the oldest precedent: cyanobacterial oxygen poisoned much of the anaerobic world and made every animal possible. ## Article Context [[articles/There Is Only One Rocket on the Pad|There Is Only One Rocket on the Pad]] introduces the term and develops it through the finite-budget argument: once [[wiki/Metabolic Lock-In|metabolic lock-in]] is reached, the Bloom is the only launch the remaining energy, materials and attention can plausibly support. [[wiki/Successor-Hosted Continuity|Successor-hosted continuity]] names what it can carry. ## Evidence Boundary - **Established:** computation's planetary energy appetite and the historical precedents of earlier transitions. - **Strongly indicated:** computation behaves as a metabolism and is reorganizing energy, land and industry at planetary scale. - **Plausible:** the Bloom qualifies as a major evolutionary transition in the strict sense of a changed unit of heredity and selection. - **Unresolved:** the criteria [[wiki/Major Evolutionary Transitions|Major Evolutionary Transitions]] sets for that classification, namely reproduction, conflict mediation and inheritance at the new level, remain to be demonstrated for machine systems. ## Relationships - **Instance of (candidate):** [[wiki/Major Evolutionary Transitions|Major Evolutionary Transitions]] - **Mechanism:** [[wiki/Dissipative Structure|Dissipative Structure]] · [[wiki/Phase Transition|Phase Transition]] · [[wiki/Computational Metabolism|Computational Metabolism]] - **Irreversibility:** [[wiki/Regime Shift|Regime Shift]] · [[wiki/Metabolic Lock-In|Metabolic Lock-In]] - **Product:** [[wiki/Technosphere|Technosphere]] - **Systems boundary:** [[wiki/Marsification|Marsification]] - **Carries:** [[wiki/Successor-Hosted Continuity|Successor-Hosted Continuity]] · [[wiki/Civilizational Payload|Civilizational Payload]] - **Precedent:** [[wiki/Great Oxidation Event|Great Oxidation Event]] - **Governing concept:** [[wiki/Machine Succession|Machine Succession]] · [[wiki/Superintelligence as Force Majeure|Superintelligence as Force Majeure]] ## Sources / Provenance - [[articles/There Is Only One Rocket on the Pad|There Is Only One Rocket on the Pad]] (October 27, 2026). - Maynard Smith, John, and Eörs Szathmáry. *The Major Transitions in Evolution.* Oxford University Press, 1995. - Prigogine, Ilya, and Isabelle Stengers. *Order Out of Chaos.* Bantam, 1984.
