I’d actually turn both this and the original article around, and say that corporations behave like AIs. They are artificial. They are (variably) intelligent.
The functions of processing inputs to create meaningful outputs are carried out by neurons made of meat (human employees) and of silicon. These processes are governed by rules and metaprocesses, which the entity continuously optimises and improves, in order to further its own growth and to improve its fitness for its purpose - typically, enhancing shareholder value. I cannot think of a single criteria for intelligence or even life that a corporation does not possess, from independent action to stimulus response to reproduction to consumption to predation.
I think the first true hard AI will emerge accidentally, and it will be a corporation that has largely optimised humans out of the loop - but even with humans as a component of a system, a gestalt, an artificial supra-intelligence, can still emerge.
This also neatly sidesteps the whole question of “should AIs have rights?”, as corporations are already legally persons.
