Picking up Go as a Java dev—what could possibly go wrong?
Good read. The differences aren't as stark as I would have imagined, but of course, the Go approach is by and large cleaner and easier to read no doubt. The Kotlin examples somebody posted in the comments (https://github.com/alexismanin/concurrency-examples-kt) are much better IMO, but Go is still the cleanest. Go's concurrency really is a killer feature.

Java 21 makes me like Java again
Java 21 doesn't retrofit green threads though. Quasar [0] is a library that implemented fibers for Java and the main developer pron has joined the OpenJDK development team. All that was necessary for first party support is to make the JDK libraries yield when blocking.
Adopting async isn't impossible at all, there is very little demand for it.

DoorDash: Migrating From Python to Kotlin for Our Backend Services
I'd say because of Erlang. Loom's architect was building a bytecode-modifying (with a javaagent) lib named Quasar before he joined Oracle. The project page mentions a news titled "Introductory blog post: Erlang (and Go) in Clojure (and Java), Lightweight Threads, Channels and Actors for the JVM." in May 2, 2013.
