Ah, I see what you're getting at! You're looking for something that captures the essence of the current age in a more material or tangible sense, similar to how the "Stone Age" or "Iron Age" represent eras defined by the materials people used.

Given that we live in an age where advanced materials, technology, and energy sources are key, here are a few ideas for a name:

1. "Silicon Age" Why: Silicon is the backbone of modern electronics, from computers to smartphones. It’s the material that powers much of our current technological infrastructure.
2. "Carbon Age" Why: This could represent the dual nature of carbon in our age—on one hand, it's central to life and organic compounds; on the other, it’s heavily tied to climate change and fossil fuels. This name reflects the complex relationship we have with carbon.
3. "Composite Age" Why: We’re increasingly using composite materials—blends of metals, plastics, carbon fibers, etc.—to build everything from airplanes to smartphones. This name could symbolize the diverse mix of materials shaping the modern world.
4. "Plastic Age" Why: Plastics, in their many forms, have revolutionized industries from packaging to medicine. They are a dominant material in everyday life, despite growing concerns about their environmental impact.
5. "Lithium Age" Why: Lithium powers our batteries, from smartphones to electric vehicles, and is integral to energy storage systems. As we transition to cleaner energy, lithium’s role is becoming more central.
