If there are many numbers, it’s easy to summarize or visualize them for quick
consumption. For example, you can quickly consume millions of numbers by
looking at its histogram, average, quantiles, and so on. If a metric has a
history of thousands of data points, then you can easily plot a timeline to
read its trend.

On the other hand, having n number of 500-word texts almost guarantees an
n-time cost to consume those texts. It would be a daunting task to analyze
thousands of historical descriptions, each having 500 words.
