Just to put it in perspective, most Scala programmers rejected Scala3 before it was even written. The Scala team, in their infinite wisdom with a collective 2 years of professional programming under their belt knew better. Nobody switched and Scala2 has been slowly dying with their neglect ever since.

PS The Scala team should have been fixing their type inference engine which lacked some important features and needed a better (Horn clause based) architecture. They did a complete rewrite instead.
