Future of reef keeping hardware

[stellarfly]

Hey guys,

I was pondering this topic the other day. What does the future hold when it comes to reef keeping hardware? Here are some of the questions:
Will running carbon and gfo still be mainstay in the next ten years?
Will protein skimmers be around? ( they have been for sometime already with very little change)
Will something replace led or is this technology just getting started?
Quieter return pumps?
Will new media be invented?
More automation making controlling tanks a breeze?

Floor is open. Would love to read what are people's thoughts on this.
