A nice benefit of the virovore though would be it would evolve to counter evolution of the virii. You could still treat with peptides &c but eventually they'll stop being effective. Against a highly adaptive organism it's probably best to employ multiple overlapping treatments. I'm not 100% sure it's this particular talk [1], but this researcher has a fascinating talk on this channel about using phage therapy in tandem with antibiotics such that bacteria resistant to the antibiotic are susceptible to the phage. Iirc they were able to clear up a life threatening antibiotic resistant infection in a patient's aorta with a single treatment. Genetic modification can be tricky in long-lived cultures, the organism you're cultivating may discard your modifications. There's things you can do to make this more difficult, but I can imagine a really general solution that works for many cultures could be super useful (say, for cultures you're speculating about productizing, but don't want to make too much of an investment in until you've characterized them better). I ran some wild west style, open air algae bioreactors for a while, and I'd fantasize about productizing organisms like this for pest control. Crazy things can happen in that sort of environment; I wasn't around at the time but there was a story about a storm which blew in from the against prevailing winds, carrying some weird kind of rotifer not normally native to that environment, and across the state people woke up to their ponds turning pink. In that kind of environment you're unable to anticipate which organisms will invade your ponds. I think it's possible those kinds of cheap, low-control methods of production will become very important. [1] https://youtu.be/xvC8xME5Zrg https://youtu.be/xvC8xME5Zrg
