Distortion Levels So Low as to Make a Brave Man Weep

It occurred to me, you can actually transmit optical hi-fi analog. How? Easy—if you're, say, scanning a near-UV nano-scale optical storage medium, you just have what the near-UV laser gets as input, be output again, say as a 532-nanometer laser (since that wavelength experiences little degradation, even across interstellar distances). That, you can then watch on something that receives those signals, or record back to other media. It's still very unwieldy compared to digital streaming, but it's also superior to digital. Interestingly, it works a lot like VHS did, back in the day, but HiFi.
