Let's write a GitHub Crawler and let's throw in everything Java (21) has to offer:

virtual threads and structured concurrency,
pattern matching and data-oriented programming,
type inference, records, and sealed types,
text blocks and template strings,
a modern HTTP client and improved collections,
modules and OS-specific binaries.

The end result will look very different from just a few years ago, let alone 10. This is not your dad's Java!
