I have yet to see anyone who argues this point show sufficient knowledge of the current state of AI research to credibly make it. If you live in the fantasy world where AI is just an arbitrary construct that can do whatever task by itself it is an easy point to make but anyone who is down and getting their hands dirty in the pile of linear algebra that makes up current AI knows that there is not even a credible pathway to creating an AGI in current research (i.e. you cannot optimize for a task you don't know at train time and if you are optimizing for a specific task you are not creating a general AI).
