Non video version is there [0]. My take on it is that there are no 'language comparisons' there. Difference is between older and newer algorithms and benchmark favorite is written in C. Its cool that new algorithms are implemented in new-ish language first.
Ah, now I think I see the misunderstanding. When I said "equivalents" I mean that these are the standard library sorts, and so I was comparing against the standard library sorts in the three popular C++ implementations.
You're correct that if you implemented these algorithms carefully in C++ you can expect very similar results. I don't believe that anybody has done that and certainly there is no sign the three major implementations would attempt to switch to these algorithms for their standard library sorts.
In Rust today the standard library sorts provided are further refinements of the "ipnsort" and "glidesort" algorithms described in the paper you linked. As the papers arguing to use these algorithms point out, the downside is that although they've been tested extensively with available tools we can't actually prove they're even safe, the upside is of course performance.
