Everyone is migrating Scala projects as we speak.

This has very little to do with Scala and everything to do with the darkside of the conference scene. Getting involved with conferences at the level she did introduces travel - drugs - drinking - partying with somewhat like minded young people. The culture at the top can be about money, stars and groupies but it revolves around power. Those in charge decide who speak. Those who speak can get opportunity and money. Money buys speaker slots.

Conferences are an anti pattern to programming.
