The continued exploration of these metals in neuromorphic computing could lead to breakthroughs in creating more advanced and energy-efficient AI systems.
Environmental and Economic Impact of the Use of Precious Metals in AI
One of the primary environmental impacts of using precious metals in AI is the mining process itself. The extraction of these rare materials from the Earth's crust can lead to significant environmental degradation, including habitat destruction, water pollution, and greenhouse gas emissions.
The energy-intensive nature of mining operations further exacerbates these ecological challenges, contributing to the overall carbon footprint of the AI industry.
From an economic perspective, the reliance on precious metals for AI hardware and infrastructure poses supply chain risks and potential price volatility.
As the demand for these materials increases, their scarcity could drive up costs, making AI technologies more expensive and potentially limiting their accessibility and adoption.
For instance, while demand for these metals is already high (gold prices could cross the $2,500 mark this year), it will hit the roof when governments decide to update their infrastructure, resulting in massive GPU and CPU purchases. This could end up making AI tech inaccessible to small businesses without huge budgets to splurge on new tech.
Additionally, geopolitical factors and trade tensions can disrupt the supply chain, leading to economic instability and potential bottlenecks in AI innovation.
