> My intuition is that as contexts get longer we start hitting the limits of how much comprehension can be embedded in a single point of vector space, and will need better architectures for selecting the relevant portions of the context.

Is it possible to explain what this means in a way that somebody only roughly familiar with vectors and vector databases? Or recommend an article or further reading on the topic?

So most of my understanding comes from this series, particularly the last two videos: https://www.3blue1brown.com/topics/neural-networks

Essentially each token of a text occupies a point in a many-dimensional model that represents meaning, and LLMs predict the next token by modifying the last token with the context of all the tokens before it. Attention heads are basically a way of choosing which prior tokens are most relevant and adjusting the last token's point in vector-space accordingly.
