It started out as an interesting history lesson told in a narrative style, but then it went off the rails and started talking about why "we" chose some random documentation platform. I'm confused

It's not really a great history lesson, it was an ironic and silly summary of events.

A better history lesson would be KEI's autobiography, which is pretty neat.

But really it's just meant to point out that k now has something reasonably resembling documentation now.

"nautical miles from radians" has to be one of the most esoteric functions built into any language.
