I Believe that all music evolves, many times over. Musical stylings will change back and forth. So What's hot today will not be in the future. I beleive artist need to be open to adaptation. The R&B genre isn''t dead., It's just got a new facelift. Production styles, the sounds, and many of the elements are quite different but some of todays sound comes from past decades stylings too. Using synths in songs is not new it just wasn't that popular in the mulltiple genres that it is now.
