It's dangerous in part exactly because it shifts the responsibility for the acts of the tool to the tool itself, and away from its author. Like deforestation was the machine's fault, not the fault of the humans driving them.
I can never agree with your affirmation that "AI is already the Architect". It is not, the AI does not design anything. It does not plan anything. It has no ideas, no critical thinking, no judgement of value or morals. The AI just does what it's told, like a tool, a worker ant, or any other algorithm. It's complicated enough that it's not obvious to us what it was told to do, but ultimately it's all it can do.
