Show HN: Scala Tutorials – interactive Scala 3 lessons in the browser | Hacker News

A Hacker News debate said Scala’s decline is driven by language complexity, weak tooling, and a fragmented ecosystem.

The Scala 2 to Scala 3 transition was repeatedly cited as painful, especially because of macro compatibility and build-tool friction.

Uncertainty around Databricks and Spark also hurt confidence among major users and slowed adoption.

As a result, many teams have shifted to simpler alternatives, further reducing Scala’s momentum in industry.
