It's neither weird nor pointless. They're going for something that is as comfortable to work with as modern dynamic languages, for something that eschews the cruft of ObjC. Python is simply a very popular representative for this type of language.
Of course, it's an easy target. But I can see why they went for it.
Yeah, I kind of get it after some additional thought (and reading through the replies).
Maybe I missed out on some detail (not watching the live video, just a text stream) – now that I've taken a look at the syntax, the comparison seems more valid. Still, comparing this to Javascript would've been more interesting (webapps, all that stuff).
