The webpagetest of the blog post is pretty telling: https://www.webpagetest.org/result/170215_26_MSDP/1/details/...

6.5 seconds to fully load the page in a desktop browser over cable modem. Over 18 seconds on a low-end Android phone. 9 web fonts loaded. Over 1.5 MB of javascript downloaded. Tracking beacons from ads-twitter, multiple "netlify.com" subdomains, addtoany, segment, intercom, mixpanel, twitter analytics, double click and GA, most of them blocking the load of the page.

TTFB is kind of a vanity metric. If you're serious about it, the way to achieve that is using varnish + edge caching rather than switching to static HTML pages. You can have good TTFB and still have a slow rendering page, as this illustrates.
