Not entirely sure if our glowforge will be able to THAT! 
lol. Lets see… even if the three dimensional control was super accurate, the GF is only accurate to withinthe thickness of a human hair (on average 100 microns say). so were 100 times less accurate than their laser. still… 36T of storage on a quarts wafer would still be pretty cool 
I should of probably tagged this as click-bait

I’m pretty sure the GlowForge won’t be able to do this… unless @dan or @tony haven’t told us about some super secret capability

I figured, but I still have to put my two cents in sometimes

Well, that would convince the aliens that we are not intelligent…
They already knew that - they’ve had GF technology for ages… they beam us up to do their “human-engraved bedside lamps” I see a photoshop image from @spike perhaps alongside the most dramatic theme song ever… lol
