Having knowledge of the technical limitations and challenges myself, I used to be on board for this argument, but now less so.
All of the technical arguments against the listening seem to ignore the "Ok, <DEVICE>" or "Hello, <DEVICE>" initiating phrases for the voluntary surveillance devices people put in their rooms, and offer only a worst case defense ~"how could they process everything everyone is saying?!"
Why is it such a stretch to imagine these devices grab Direct Objects and Subjects and store those singular items for ad keywording?
We have cookies and know how they work, why is it difficult to extrapolate?
simonw is a breathless proselytizer of LLMs and likely is suffering from "a man's salary depending on misunderstanding" and all that.
It bears repeating, "these corpos are raising billions and hiring former alphabet heads to their boards for reasons other than just making you a better programming assistant."
