There’s probably quite a few specific viruses and bacteria people 100 years from now will be astonished we just lived with in our bodies, but it seems unlikely that having a lot of bacteria and viruses in general will be seen that way. I guess it’s possible that we will develop non-bacterial alternatives to the beneficial bacteria and viruses that exist, but it’s not clear what the advantage would be.
