Large Context Does Not Equal High Efficiency

The core point is that while larger context windows are beneficial, stuffing them with low-quality information doesn't help.
The author argues that as context windows grow by roughly 30x annually, the issue isn't "how much content can be included," but "whether these tokens are actually useful." The model still has to process all inputs, so garbage context wastes compute and degrades overall performance.
The conclusion is straightforward: the future isn't about "less context," but less waste.
