Moore's Law

This 'law' isn't a physics law and, highly likely, won't remain true forever. In fact, the production of silicon chips got slower in recent decades, which violated the law.

Creating a chip smaller than an atom is currently unfeasible, which poses a physical limitation on that law. In addition, chip and other component production costs might be an obstacle. Costs increase every year, slowing down the chip production.

Facing these limitations could actually result in scientists considering looking into new technologies that are not affected by these obstacles and that will make computers in the future even smaller, faster, and better.
