I'd love it if you could ask technical questions on the discord channel, as that's more scalable for us. Some quick answers:

1) We're likely to change the reference syntax to inout: https://github.com/modularml/mojo/issues/7

2) they're the same thing. Consume is the word we're currently using for the operator, owned is the argument convention. We may need to iterate on terminology a bit more.

3) Because it composes properly with chained expressions: `x.foo().bar().baz^.do_thing()` vs something like `(move x.foo().bar().baz).do_thing()`
