Maybe Cardano will, maybe it won't.there's an opinion that Cardano's not so promising and has demerits, e. g. the speed of working on projects is too slow, so we won't see a leap in the nearest future!
Yeah, as we notice cardano look interesting and has a strong technical background, but I guess it takes a long period of year before etherium will totally destroy.
