If I were a betting man, I’d put >20% odds that this or a successor technology reaches nearly ubiquitous deployment in the first world within 10 years. t.co/aDrWKLTjFH

“Define ‘nearly ubiquitous.” As common as smoke-free air, and likely through similar mechanisms.

“Meaning what.” Meaning that if you recirculate air to customers without cleaning it first your air will be illegal in e.g. New York City, and you will be fined.

This will cost many, many billion dollars in CapEx and have an ROI measured in, oh, weeks?
