[Epistemic status - I have no idea what I'm talking about.]
Could you set up a futures exchange, with physical-delivery contracts, around various PPE types? From my extremely naive understanding, couldn't this direct more capital available towards PPE production, plus as an ancillary benefit act as an implicit prediction market of pandemic risk?
I haven't thought this all the way through, but the potential to push more capital toward production, transparently allocate supply, and also get a warning signal seems quite appealing on first blush.
I don't necessarily agree but don't want to say more.
One concrete goal would be something simple where a small team of people collects samples from volunteer travelers around the world and then does a full metagenomic scan for anything that could be dangerous.
Could you feasibly get the same information from airport waste collection? I'm thinking of an airport/travel focused BioBot, but with pathogen agnostic ambitions.
