I don&#x27;t remember which conference exactly, but I do remember the gist of the complaints. In no particular order:<p>- tooling (such as sbt) is still poor, even after years of complaints and calls to fix it.<p>- no real roadmap for improvements to scala itself in the near future<p>- Dotty being a diversion for the core team, detracting from scala<p>Now, I only dabble in Scala, so I couldn&#x27;t really comment on any of these, but I did get the impression that there&#x27;s a lot of un-happiness amongst core users of Scala.
