Jeff Bezos loves space exploration. He loves O'Neil's vision of orbital colonies, and he firmly believes that moving heavy industry to orbit will leave Earth better off. That's not a vanity project.
The Washington Post, on the other hand, he purchased as a trophy. That's the vanity project.
I disagree. The poet Gary Snyder thought space travel was unimaginative - that living life as things are on earth was more interesting and challenging. Owning the Washington Post gives him control over a high visibility U.S. news operation. Nothing vanity about that.
