So far a combination of a Swedish (no carantine, just recommendations and focus on elders, reduced damage to economy) and South Korean (a lot of testing, massive usage of masks) approaches seems the best long-term solution to me.
I was thinking about it a lot recently... This is pure speculation but I believe with both infrastructure and algorithms / data science we ended up in a sweet spot: ordinary algo-traders and small teams are quite unlikely to get that far and big guys don't care about "pennies" we're making due to their fixed costs (salaries alone in a hedge fund would make our current strategy non viable).
I was originally writing this article for a general audience of Medium but if you have more technical questions within the range of what I can share, I'll do my best to answer them in the comments
