That's missing the point, you were not a slave because you're a Gaul, Ethiopian, etc. The Romans didn't see the people they enslaved as naturally only fit for slavery because of their ethnicity.
Romans saw literally the entire world as only fit to be ruled by them as not only natural, but divinely preordained rulers. They were openly supremacist and bragged about it. They didn't set out to literally enslave the entire world just to make a point, but neither did modern Europeans, because neither had to.

What they didn't do is justify slavery by saying enslaved peoples were less than human.
They didn't use that term, because it doesn't make sense before Linnaeus and Darwin, but the spirit of their worldview was the same. They also didn't feel the need to justify it at all. To them, it was not a "peculiar institution" that needs theoretical defense against its detractors, it was completely normal, the default state of things.

I don't think they thought people were savages because of their ethnicity or genes, but just based on their culture. Roman citizens had rights and could not legally be enslaved, but citizenship was not exclusive to certain ethnicities.
This type of fairly inclusive Romanitas developed quite late as a response to the demographic reality of the Empire, not unlike say Britishness has been redefined after WW2. But for most of their history they were very ethnos-minded. Having common ancestors and ancestor worship was the cornerstone of Roman culture and religion.

Also in the unlikely event that there are people left to say anything 2000 years from now I hope they'll have a more nuanced view than that.
No, they will meme about how Europeans were open-minded, peaceful traders and knowledge-sharers, because Portuguese missionaries in Kongo or the Moluccas were a thing and Pushkin and Dumas were 1/something black, just like you people meme about Rome
