Besides shrinking and increasing size chips, there is another big problem that might cause us to hit the wall. When the transistor count increases, it also increases the amount of effort. This is a big problem because chips need to be profitable. Although if you just shrink the chips and keep the transistor count the same, then you have a more energy efficient chip. Which is especially useful for portable devices.
