I would assume many consumers are gonna have to switch to more of DIY approach for many tasks that required some domain expertise. For example, most of my friends completely stopped buying useless skincare products because chatgpt would make them a table of INCI list and explain them the benefit of the ingredient. Turns out most of products are BS. Vitamin C doesn't even penetrate the deeper skin layer, it just evaporates on your skin. My bet is that many companies will have hard time marketing on customer's naivety.
