That's why I made reference to a generic "mega civilization".
We're talking hundreds of millions of years from now, the only safe bet is that "humans" as we understand them won't be around. That would be as weird as the vernacular language of a people being an English we would understand, in 100,000 years!
Our descendants might be a mega-civilization. Our creations might be, or rather the descendants of our creations. We might get wiped out by an alien von Neumann probe, get wiped out and then get von Neumann probed, or ordinary colonization, or, maybe we'll uplift the rats and they'll overthrow us, or dolphins will come back on land and grow thumbs!
By then things would be so different it's impossible to imagine what humans might do or be capable of our interested in - if we're still around.
