The comparison with kevlar and titanium is weird, as they don't compete in the same category of strength and they are not the strongest in their categories. "I heard kevlar is used in flak vests, so it must be strong" is not a scientific argument.
Titanium is a pretty bad comparison. Its 10-20x weaker, and is also weaker than fiberglass, nylon, most steels, sapphire, many other types of metals and fibers...
Though the pop article is light on details.
