Undoubtedly many of us, most of us?, have 1,000, 2,000, 3,000 year-old paintings, pottery, mosaics and unclassified objects of dubious provenance that need restoring. Why can’t we use our laser? Clearly, this is something glowforge needs to work on.
Sure it is a Er:YAG laser, but how much difference could there really be? And note their filter - it’s the thing that looks like a pneumatic tube hanging down from the ceiling. Not only is it great for removing smoke, but if you accidentally free an ancient ghoul, ghost, curse, etc… it’s efficiently whisked away.
