Compressing capable representations is easier than enhancing compressed ones

In a discussion on optimizing Qwen indexes, the author argues that while storage can be reduced, dense vectors lack the performance of multi-vector/late-interaction methods. The core insight is that it is easier to compress a more capable representation (e.g., with long context or OOD generalization) than to make a compressed representation more capable.
