1. The obvious thing is that technology (and various things we’ve called AI over time) actually has given laundry robots and dish washing robots. Her follow up tweet said of course she knows and that she's joking, but the joke/criticism relies on those things not existing. I kinda think she just forgot, as we all do, as we take technology for granted.
2. Second takeaway was the same as you, with all the free time we have now—and the free time we hypothetically would get with laundry AI—hard to believe we’re really going to start our great American novel.
3. Her follow up was something like “I don’t actually mean laundry and dishes, I mean it metaphorically”. This just read to me as "I just want things that I want. And don’t want things I don’t want. Don't ask me what those things are." We all do, but it muddles any potential wisdom in the quip if we can just swap laundry, dishes, writing, and art for whatever.
So basically a nothing burger about what AI is today or should be, but loud expression of that nothing anyway. I thought it was more like a spitball take (albeit a tad clickbaity and trolling) and had it gotten lost in the wind it would have been fine, but it going viral said something about current opinion.
