Ultrafast laser manipulation of nanoscale magnetic vortices reveals systemic bottlenecks in spintronic scalability and energy efficiency for next-gen computing

Indigenous perspectives on energy and computation emphasize cyclical, regenerative systems over linear, extractive models. The focus on ultrafast magnetic switching ignores the cultural and spiritual dimensions of energy use, such as the Māori principle of *kaitiakitanga* (guardianship), which would demand accountability for the environmental costs of nanofabrication. Traditional knowledge systems also highlight the interconnectedness of magnetic phenomena with natural forces, offering alternatives to the mechanistic view of spintronics.

Spintronics emerged from Cold War-era research into magnetic materials for defense applications, with early breakthroughs tied to the Manhattan Project's legacy of materials science. The development of giant magnetoresistance (GMR) in the 1980s, which underpins modern hard drives, was a direct outcome of military-funded research. The current focus on ultrafast switching echoes earlier cycles of hype around 'revolutionary' computing paradigms, such as Josephson junctions in the 1970s, which failed to deliver on scalability promises.

Cross-culturally, the metaphor of 'brain-like' computing reflects a Western bias toward individualistic, hierarchical models of intelligence, ignoring collective and distributed forms of cognition found in many non-Western societies. In India, the concept of *chitta* (consciousness as a field) offers a non-binary framework for information processing, while in Indigenous Australian traditions, the Dreamtime's interconnected narratives challenge the discrete '0' and '1' logic of spintronics. These perspectives highlight the cultural specificity of the 'brain-like' computing paradigm.

Scientifically, the ability to switch magnetic vortices at picosecond speeds is a significant advancement in ultrafast spintronics, with potential applications in energy-efficient memory and logic devices. However, the energy efficiency of these systems remains a critical bottleneck, as laser-induced switching often requires high power densities that generate heat and degrade materials. The lack of standardized metrics for energy per operation in spintronics further complicates comparisons with traditional CMOS technologies.

Artistically, the visualization of magnetic vortices as 'spinning' entities invites poetic interpretations of quantum entanglement and non-locality, resonating with abstract art movements like Suprematism or Indigenous dot painting. Spiritually, the focus on angular momentum and vortices echoes ancient cosmologies, such as the Hindu concept of *kundalini* (spiritual energy as a coiled serpent) or the Greek *pneuma* (life force as a whirlwind). These metaphors challenge the purely mechanistic view of spintronics and invite interdisciplinary dialogue.

Future modelling of spintronics must account for the rebound effects of energy efficiency gains, where increased computational power leads to higher overall energy consumption (Jevons paradox). Scenario planning should explore decentralized, community-owned spintronic technologies to avoid the pitfalls of corporate monopolization, as seen with semiconductor supply chains. Additionally, the integration of spintronics with neuromorphic architectures could redefine computing paradigms, but only if coupled with circular economy principles to mitigate material scarcity.

Marginalized voices in spintronics research are often sidelined by the dominance of Global North institutions and corporate R&D agendas. Workers in rare earth mining communities in Congo, China, and Myanmar face exploitation and environmental degradation, yet their perspectives are absent from narratives about 'technological breakthroughs.' Additionally, women and non-binary researchers in STEM fields are underrepresented in spintronics, despite their critical contributions to materials science and nanofabrication.
