I don't agree. There are so many niche genres now that have never existed before, e.g. vaporwave, phonk, outrun, twee, etc. Gotta dig deeper. There is tons of fresh and original underground music being made still.
As a fan of both, I have to admit vaporwave and twee are both dead genres - although vaporwave has spawned a host of successor stuff, the great innovation there all happened a decade and more ago. Twee will always exist, but it's hardly a great example of a lively scene.
