I'm not disagreeing with the general thrust of your comment, which I think makes a lot of sense.
But the idea that an AGI must start out with the ability to parse human languages effectively is not at all required. An AGI is an alien. It might grow up with a completely different sort of intelligence, and only at the late stages of growth have the ability to interpret and model human thoughts and languages.
We consider "write fizzbuzz from a description" to be a basic task of intelligence because it is for humans. But humans are the most complicated machines in the solar system, and we are naturally good at dealing with other humans because we instinctively understand them to some extent. An AGI may be able to accomplish quite a lot before human-style intelligence can be comprehended using raw general intelligence and massive amounts of data and study.
I agree that natural language understanding is not a necessary requirement for an early AGI, but I would say that by definition an AGI would have to be good at the sort of cognitive tasks humans are good at, even if communication with humans was somehow difficult.
Think of making first contact with an undiscovered human civilization, or better, a civilization of space-faring aliens.
... raw general intelligence ...
Note that it is unclear whether there is any way to achieve "general intelligence" other than by combining lots of modules specializ...

My own projection goes more like this:
At least one clear difference between my projection and Yudkowsky's is that I expect AI-expert performance on the problem to improve substantially as a greater fraction of elite AI scientists begin to think about the issue in Near mode rather than Far mode.
As a friend of mine suggested recently, current elite awareness of the AGI safety challenge is roughly where elite awareness of the global warming challenge was in the early 80s. Except, I expect elite acknowledgement of the AGI safety challenge to spread more slowly than it did for global warming or nuclear security, because AGI is tougher to forecast in general, and involves trickier philosophical nuances. (Nobody was ever tempted to say, "But as the nuclear chain reaction grows in power, it will necessarily become more moral!")
Still, there is a worryingly non-negligible chance that AGI explodes "out of nowhere." Sometimes important theorems are proved suddenly after decades of failed attempts by other mathematicians, and sometimes a computational procedure is sped up by 20 orders of magnitude with a single breakthrough.
