Stuff like this is probably mostly tech demo, but there are instances where it could make jobs safer (hot work in locations with corrosive or explosive gases nearby, such as at a chemical plant, underwater welding site, responding to gas leaks, etc.
Watch the USCSB channel on YouTube for good examples of dangerous jobs, such as putting out uncontrolled chemical fires, or performing hot work during the most dangerous times at chemical plants, when stuff is shut down for maintenance and might still be leaking catalysts. Robots could save lives.
This is a seriously cool article. An accretion disk tens of thousands of light-years across is fucking wild. That’s getting awfully close to our own SMBH at our galactic core, sag A* if LID was placed between us and our SMBH.
A fucking plasma of superheated matter from a black hole could be crisping our black hole and Earth simultaneously. Jesus.
