In this context, the term "Artificial Intelligence" refers to a man-built emulation of the physical process that allows humans to reason and shape the world around us in pursuit of our goals. This hasn't been achieved yet, but humans are proof that it is physically possible. (And through evolution, which is not a strongly guided process). Unless you believe there is something inherently special and unique about humans that make it impossible for this physical phenomenon to be replicated artificially, there is absolutely something to worry about here.
