I disagree, and I think you'll see what I mean when you shift the frame of reference from "person working at a large company with Office 365 installed" to a couple hundred million average Joe's having access to it at home.
Webs search is now a horrifying wasteland, and people know it. Remember the conversations we all had just a few years ago: LLM will replace web search. That's the key point here - not "replace web search" for the subset of people who have office jobs, but web search for the vastly greater number of people who just have it at home on their computer.
The tech - the products - are good enough for your average person at home who wants a starting point and a structure to work through for something they know nothing about. I think that's actually one of the strengths of the tech as it exists for the winder audience: you don't really need ultra accurate, super precise, info and checklists and guides when you just want to know what to look into to do some decorative tiling on the top of an old table you bought; a way to make sense of and work through a type of pop media you have become interested in; to give you a starting point to work through some new problem you have encountered in day to day life.
That "80 percent vaguely accurate-ish" threshold that LLMs can broadly deliver for a novice is actually good enough for that vast majority of things people deal with that aren't really super-critical. Are you idly curious about some ways to think about how to replant and re-do your back yard greenery? Curious about how to make sense of all the competing numbers and criteria and features when looking to buy your first air-conditioner? Want to take a vague, repetitive, not very well put together response to something your neighbor starting holding forth on on Nextdoor and make it tighter and better expressed?
That little Copilot icon that comes default in Windows legitimately can help you there.
