The rest of it is the main point.
Given that it's likely to be very very popular, and nobody can claim to be an expert, you can be one of the most knowledgeable people in the world about it by getting in now. Want to be the author of a very popular framework in a very popular language? Write a framework now in Swift.
Write a framework in Swift if the abstractions it introduces are considerably better and more conceptually complete than the existing tools.
Otherwise you're not really improving things, just piling on more crap for people to learn.
Seems like a fairly clear point... What I don't get is why making that point needed the "I know more ObjC than you do" preamble.
Just seems like he didn't even know where he was going with this article.
Because it's a prediction about internet, community, and people's behaviour, based on the previous knowledge about languages. Not based on the knowledge of Swift. It's a commentary about people jumping on the language that is likely to be pushed very hard by Apple - whether it's ready and useful or not.
That's a weird way to start an article. I was hesitant to read the rest. And the rest of it was a mixed set of odd arguments, e.g. "I predict with great confidence that Swift will be TIOBE’s language of the year."
I have no idea why would I be interested on your prediction on a not-very-useful index.
I don't even understand his argument: he is complaining that normally languages are evolved in small circles before publishing, and says that Swift has come naked, half-baked, to the world but then also remembers to say it isn't even released (!)
