The Great Concurrency Smackdown: ZIO versus JDK by John A. De Goes

[Robert Engels]

Sorry, I should have given more context. It appears the Scala community is suffering from some political??? issues - to the point that the speaker in the cited video has been “cancelled” and disinvited from the upcoming “scalaconf”. Doesn’t bode well for its wide adoption - which was already in decline.
