I think that’s really the leg-up Glowforge has, that they’ve simplified the physical user interface so much (to the single button) that everything else can be done in software. It’s the shock that Blackberry had when the iPhone came out with only a single button.
I don’t even know where Glowforge can go after this. Everything is in the cloud, all the updates are just there when they’re released. The physical hardware has been reduced to that button. Maybe larger cut areas? Bigger objects for the pass-thru? Faster motor speed?
