In around 10-15 years, silicon will effectively not be able to supply us with anymore speed like it does today. Researchers are looking for ways to overcome with wall.

This method allowed the scientists to create digital-logic elements that are 260,000 times smaller than the ones used in the most advanced semiconductor chips available today. Putting that in perspective, the most complex circuit they built--a 12-by-17 nanometer three-input sorter--is so miniscule that 190 billion of them could fit on top of a standard pencil-top eraser. A nanometer is a billionth of a meter, which is the length of about five to 10 atoms in a line.
