This is not a writeup of "Ada is better than everything else". The author is explaining how Ada achieved safety/reliability goals that your favorite language independently evolved much later on. That is why they kept bringing up year-of-arrival for comparison.

Examples would be a nice bonus but I think the author eschewed such because they weren't interested in writing a tutorial. They had a very specific point to make and stuck to it, resulting in a very informative but concise article that reads well because of its highly disciplined authorship.
