I do mean it even more generally than you're interpreting it, so no argument there. I'm not applying attention to software at all. Attention is part of the demand function for a certain kind of consumer software, which can be a leaf node, but not software generally. Attention-based software products are certainly threatened.
How else to word this…
I'm not casting aspersions on art. There is a finite amount of content we can consume but maybe not software processes we can coordinate.
