This doesn't actually change what I said. The imagined future is that people just use agents for shopping. Assuming the capitalistic economy we have constructed remains (and I've little reason to think it will vanish anytime soon), poor people, or people with low incomes, are certainly not going to be using high-end or even midrange models/agent providers. They will go for whatever sounds the best and which is the cheapest, regardless of it's quality or how gullible it is. So attempts like tfa to figure this problem out now are very useful indeed.
