The headline first, even though it buries the lede: ACE 2018, the 15th International Conference on Advances in Computer Entertainment Technology, has invited former Breitbart News executive chairman and former Donald Trump White House chief strategist Steve Bannon as a keynote speaker. ACE is a smaller, but long-running academic conference on, as it says on the tin, entertainment technology. If you ask: Why does a smaller academic conference on entertainment technology invite Bannon as a keynote speaker, you are not alone. The announcement has led the second keynote speaker, play researcher Peter Gray, to withdraw from the conference, and numerous researchers to publicly call for boycotting ACE under the #boycottACE hashtag.
