Disagree. Simply "doing something better" is not disruption - that's just business as usual. Disruption is radical change through technological innovation. The author seems to think that all industries are equality ready for that sort of shift. I'd argue that Facebook didn't disrupt social media: it just overhauled MySpace/Bebo and expanded the online advertising "disruption" instigated by Google. eBay and Amazon disrupted the retail shopping industry, but building a better eCommerce site isn't more disruption. There is also the question of how easily radical change can disrupt an industry. Weapons manufacturing could, for all I know, be swathed in unnecessary beaurocracy and be mired in ancient technology, outdated processes and unnecessary overheads. But it's fair to say that the industry is unlikely to be 'ripe' for anything without some sort of monumental policy changes at government levels. The exception that proves the point is the space industry: a shift of government policy lead to actual disruption by SpaceX.
