I do have the theory that the more untyped the language is, the larger the islands are: Fronterra (JavaScript), Cloudderra (YAML), AILandia (Python) are way bigger than Java, Swift, DotNet, etc. even though the prejudice saying goes that the problem of software engineering is stale old enterprise code in Java/DotNet.
That might be the case, but the libraries seems to be more reusable!
