Edit: and to add more so this response isn’t purely trash talking: plenty of us have already switched over to using ChatGPT/bing for our standard question answerer. It is far more efficient than getting back pages of search results and having to parse through garbage site after garbage site, scrolling through pages of ads and SEO optimized copy to look for the one nugget of info.
The thing is, people will adjust their usage patterns for these bots just like we did for search engines. You don’t just 100% believe what the first webpage says. You look for other contextual information to determine if you believe it or not. That is a learned pattern to how we consume search engines and a similar thing will happen with LLMs.
It’s like, if you were the first person to come into contact with fire, you reached your hand in and got burnt and then declared that fire is useless because it burns you. In either case, for LLMs, search engines, or fire, if you use them incorrectly then they won’t be useful. It’s up to you to use them correctly.
