I am not so sure about that. The modern web has become complicated/unusable enough that I can see a lot of people prefering a chat interface over having to click through this unholy mess. I might be biased, as I have to deal with accessibility ussues on a daily basis. However, there is a whole demographic we're currently leaving behind. There are a lot of people around who simply don't try to use the Internet to get things done, because they are overwhelmed with how it works. My mother doesnt even want to click on a YouTube link sent to her via WhatsApp, because she would leave the well-known app and have to deal with the web... However, I can imagine her using an agentic interface to get things done, although not right now, maybe in 2 years.
