I remember getting excited back in 2013 for PS4 and PSVR because I thought we'd be able to watch footage from NASA satellites on stream, live, on planet surfaces and shit.
Man...I was a dumbass for that one

Planetary atmospheres don't take kindly to our tech after all, especially ones like Venus :S. BUT, if something could be figured out to, maybe, get stream feeds of live footage from the ISS and roaming satellites flying around the Earth that we could watch in VR, that'd be absolutely amazing tbh.
Maybe it's unoptimized? Let's hope so.
I agree to an extent though; RT will have to be used selectively and smartly (and mixed with "fake" RT-like effects and techniques artistically) to get the most of it this gen at wide scale and optimal levels of performance in framerate.
