At the risk of becoming the infamous iPod and Dropbox posters, I really don't think so. My browser having an LLM directly integrated adds nothing for my use cases that couldn't be accomplished with a web service or dedicated tool/app. For me, an integrated LLM running concurrently with my browser just represents a whole lot of compute and/or network calls with little added value and I don't think that this is unusual.
Having something that read everything I read and could talk with me about it, help remember things and synthesize? That’s awesome. Follow links and check references.
Better yet, if an LLM does add value to the use cases why is it that I have one "integrated" LLM when editing a document in the webpage, another "integrated" LLM in the browser, and then an "integrated" LLM in the OS. If there is value to be had I want it to integrate with the different things on the system as they exist just like I do, not be shoehorned into whatever company abc decided to bundle with just their product(s) too.
