I use ChatGPT to find products and opinions about those products, same way I'd use Google. I'd never just click on the top sponsored result in Google and buy it, and I'd never just click on a result in ChatGPT and buy it. And yeah, there are lots of reasons I might change my mind in the future - I no longer buy anything from Amazon, for example, because there's no way for me to trust what I'm getting. But right now it's a great way of researching options.
