from Live Science:

Silicon may represent one of Earth’s more common elements, but it transformed Silicon Valley into a high-tech corridor and helped usher the world into the Information Age.

Lots of geopolitical issues here, but the bottom line is that we need to find or develop a new variety of sustainable ‘tomorrow building’ materials. Other considerations: Defense Industry to Face Shortage of Key Materials
