"If you consider the amount of information that changes on a daily, or even weekly basis on a site like wework.com, it is actually quite wasteful to have a server process each and every request that comes through."
A better solution for a marketing site is to use a CMS (doesn't really matter which - Wordpress, Rails, etc) and then use a CDN like Cloudflare to proxy static pages and speed things up. It's fast, efficient, and flexible.
The solution wework used optimizes for performance but reduces flexibility. I'd bet the marketing team at wework wishes that they didn't have to redeploy the entire site every time they wanted to change some text.
