You conveniently left off the next part of that sentence: "(hint: much of it is not)" It's pretty clear that ddevault thinks that Gemini can replace a large fraction of the web (which is the issue under dispute).
The difference between "Gemini can replace the whole web", "Gemini can replace a large fraction of the web", and "Gemini can replace anything more than a vanishingly tiny sliver of the web" is largely irrelevant, as all of them are false, and my argument reads the same if you substitute either of those other two phrases in.
