Its an experiment, Jesus. Imagine how much 3d printers will improve within the next decade (especially considering how much they have improved in the last) - some serious implications for being able to "print" your own dubplates at home on the cheap. Pointless, I think not.
While it's at the infantile stage, it could be promising in the long run. I wonder how long but won't lose sleep or waste too many 0's & 1's over this one. Like many things, the initial stage looks unpromising but given the real status & upkeep of lathes, this could be very promising if it evolves to the point where it exceeds/corrects some of vinyl's accepted flaws, limitations and they get it really right.
Regardless of sound quality in the current state, this is ridiculously badass. I mean, I remember thinking it was badass to be able to play an LP and record it onto a cassette, so perhaps I'm easily impressed. Even if I am, this is just merely scratching the surface of something that could be BIG. Can't wait to see where this technology eventually leads!
