It's great to see that even software engineers, 'geeks' considered socially less apt, are recognizing that technology is simply extension of human capability. Unless technology is doing that one thing, it is useless. No matter how amazing or innovative a new widget is, unless it is useful to people somehow, it is pointless.

Regarding phages, I am also very glad to see this kind of research. The solution to antibiotic resistance is diversity of vectors, and phages are a new, or relatively underutilized, vector of bacteriocide. I note that something that hasn't been undertaken even conceptually is the inverse.

There are numerous companies presently working on viricides. Given the current Wuhan situation, this effort is lent urgency. One of the most promising mechanisms are nanodevices which mimic cells and trick virii into latching onto the devices with the structures they use to attack cells. The devices then trap and destroy the virii. I suspect that bacteria can be engineered to perform this role, and even to be sustained on a diet of pathogenic virii, while also being self-replicating and not requiring economic and industrial manufacturing to produce after their initial engineering.

Thanks!
