Earlier quoted context omitted.
Yes, of course it's different. Google can point you to a real Wikipedia article while GPT-3 will generate links to fake ones (or you could ask it to generate a fake article.) It's the difference between truth and fiction. Or at least, a first-level approximation. Wikipedia articles can be wrong.
Well google also can point me to fake links with no real content at all as well. But I get your point.
E.g
Ask "is pi disjunctive" and you'll get the top result of
> = 3.1415926535897932384626433832795... is a disjunctive number.
But if you click into the article (what percentage even will?) you'll find it's part of a larger statement:
> It is not known whether π = 3.1415926535897932384626433832795... is a disjunctive number.
