When silicon hits its limits, go 2D! Penn State just created the world's first atom-thin computer using molybdenum disulfide instead of silicon. Their breakthrough proves that sometimes the path forward is literally flatter - these 2D materials maintain peak performance where traditional chips fail. 
science.slashdot.orgWorld's First 2D, Atom-Thin Non-Silicon Computer Developed - SlashdotIn a world first, a research team used 2D materials — only an atom thick — to develop a computer. The team (led by researchers at Pennsylvania State University) says it's a major step toward thinner, faster and more energy-efficient electronics.
From the University's announcement:
