I think the real reason is that Chris Lattner doesn’t want to work on Julia. He’s likely very (and justifiably so) opinionated about these topics, and probably wants a certain degree of creative authority over his projects.

Maybe I just misunderstand it from the presentation format.

He works on Mojo a lot, mostly on weekends. In the past few months, he has worked on strings, collection literals, dependent types, reference captures, comprehensions, and many other nice language features.
