Passage Summary: Making computer chips smaller usually makes computers faster, but right now, we can't shrink them without making them worse, so we're stuck at current speeds.

Conclusion: We are currently unable to make computers significantly faster.

Reasoning: While shrinking a CPU chip without losing sophistication increases speed, we cannot currently shrink these chips without a loss in sophistication.

Analysis: The author identifies one specific method for increasing computer speed—shrinking the CPU— and then explains why that method is currently stalled. To conclude that computers cannot be made faster *at all*, the author must assume that shrinking the CPU is the only way to achieve that speed boost. When tackling this, look for an answer that bridges the gap between 'this one method is unavailable' and 'the goal is impossible.' If there were other ways to increase speed, like better software or different hardware architecture, the argument would fall apart.
