Yea, if the author is only thinking about text data, then maybe they'd have a point. But the world in which 'intelligence' exists only a tiny bit textual. Visual then audio data represent most of what humans interpret. And who knows what continuous learning will look like.
If you believe we are moving towards the more 'star trek' like future of AI where AI observes and interprets the world as humans see it and experience it, a massive amount of compute is still needed for the foreseeable future.
If you believe we are capping out on AI capability soon for some time, then you'll see AI as more of part of the "IBM toolkit" offered as an additional compute service and it will more likely 'fit' in our existing computer architectures.
