Having an internet connection, a proper AI can easily order contractors around and reproduce, secure and empower itself.

I mean, that's the standard idea guys like Yudkowsky talk about. Having poked around a bit, it seems a couple decades of petty hackers have made that pretty impossible to do without either leaving a meatspace paper trail, or having meatspace human accomplices. Conquering the world instantly by Wifi, unless you can break encryption, is probably overblown - for now.

Otherwise, I just agree.
