A moat refers to protections from competition. There is also the opposite of a moat, an ultimate siege weapon. If a moat is a defensive obstacle then the opposite is any new technology that both ignores any current obstacles and simultaneously is too expensive to fight. An example would be the Gutenberg Printing Press or railroads in the 18th/19th centuries (industrialization). Those technologies simply walked past current approaches like they weren’t there and produced cheaper output than the prior approach could possibly dream. Worse, competing with such ultimate siege weapons is more expensive than ignoring them until they kill you. What’s surprising is that any such ultimate business siege weapons are typically well known for years while they develop slowly until they actually figure out how to work and are ignored due to bias until it’s too late.
