I became very unpopular very quickly at work for a while, when I said that the UV robots used to sterilize rooms were pointless. They were like, OMG, $80K machines are used to disinfect the Rona! And I said that since the virus was bullshit, that the whole point of buying the machines were for money laundering. I didn't think that they were all that effective anyway, since you still have to clean the room anyway. Before and after. Gotta love it when the year-long narrative falls apart.
