It's not an indiscriminate lossy compression though, it's a summary your brain finely tuned for a specific audience: yourself.
What's cool in this whole intelligence process is we get to refine the algorithm of what exactly it is we want to keep in the summary.
In "discarding features that aren't relevant" mentioned in the article, we subconsciously pick what is and what isn't relevant.
That's why I think we sometimes have such vivid memories of some childhood scenes: something new happened, our algorithm at that time didn't know what was "relevant", so out of safety it decides to store everything.
