To the extent that a dichotomy between "biological, evolutionary evolved intelligent" life and "superintelligent robots" will even make sense in the far future (utopias, dystopias, in most any scenario in which intelligence still exists), we'd probably refer to ourselves as "superintelligent robots" at that stage.
The idea that long after a point when uploading was feasible, we'd still stick meatbags in spaceships to travel to distant stars, is somewhat ludicrous. Unless aliens, for unknown quirks in their utility function, really value their biological forms, and got negentropy to waste, it's a no-brainer that they'd travel/live in some resource-optimized (e.g. electronic) form.
There will always be a causal link from an "artificial" intelligence back to some naturally evolved intelligence. Whether we call the invariable "jumps" in between (e.g. humans creating AI) as breaking that link, or merely as a transformation, is just a definitional quibble. After a certain point in a civilization's evolution, we'd call them "robots" (Even if that word has some strange etymological connotation, since the majority wouldn't necessarily be 'working'.).

A causal link yes.
we'd probably refer to ourselves as "superintelligent robots" at that stage.
But only if we did manage to enhance or upload or whatever else during the transition with the distinguishing feature that we'd perceive this as a continuation of our identity.
But if we created a AGI that didn't care for our values and facilitated our transition but just did whatever else its utility function decreed than y...
An Article on Motherboard reports about Alien Minds by Susan Schneider who claiThe Dominant Life Form In the Cosmos Is Probably Superintelligent Robots. The article is crosslinked to other posts about superintelligence and at the end discusses the question why these alien robots leave us along. The arguments puts forth on this don't convince me though.
