In the past couple years, you may have found yourself wishing that all the viruses in the world just disappear. But be careful what you wish for...

    well, for one thing, there certainly wouldn't be any viruses
  • @Dee-jp7ek
    My mind immediately thought of bacteriophages and how we'd all probably die from bacterial infections without viruses to hunt them down
  • @InTheAKSnow
    I'm very surprised you didn't cover the fact that once upon a time a retrovirus infection was responsible for introducing the genes to produce syncytin, which is vital for the placenta and we would not be able to exist as we are without it.

    "I wish for a Professor Farnsworth 'What if...? machine' to accurately find out what the consequences of wishes would actually be before I made them!!!"
  • @MonkeBrain07
    Yeah, this needs to be taught at schools. Schools tend to focus on pathogenic viruses and omit other details.
  • At my university there is a freshman lab that focuses on the discovery of new bacteriophage and has each student or group of students collect a dirt sample. The sample is then tested to try and find a new type of bacteriophage, and because of how common they are and how little we know about them it is very very likely that at least half of the class will discover a completely new virus
  • @EOTBuk
    I am no virologist, but I would consider that even pathogenic viruses have been useful in history to help keep animal and plant populations in check.
  • @curls22
    I'm gonna be real- my favorite part of these videos is the list of sources and picture credits at the bottom of the description. I love this. I wish all channels would do this when they're referencing something or talking about something that could definitely benefit the viewers by sharing their sources.

  • @odomobo
    "As much havock they've wreaked throughout history, scientists are starting to understand..." We need to do something about these scientists
  • @MolestedDonut
    I'm in the 2%. Now just gotta figure out how to get to the 0.01%
  • @henrykrider179
    I remember in a video on COVID there was mention of basically 'viral niches', where different viruses might specialize towards different tissues (like lungs vs throat for respiratory diseases), and with benign viruses in the body I wonder if any of them provide some buffer against new viruses by occupying a viral niche. May be more likely in the digestive system if the virome is essentially a pair to gut bacteria, but idk, it's an interesting thought
  • @nolakillabeast
    I have a gastro virus right now, literally feels like dying, but I know there is a war inside of me. I am so proud of my little soldiers that keep this virus at bay within 24h, but why don't they learn??? I get that gastro virus every year !!
  • @Kittsuera
    I get the feeling someone found a Genie and was asking this question “for a friend”
  • @wcookiv
    It's always seemed to me like the most intuitive way to view a virus is to consider the infected cell to be the mature organism and the virion to be a spore or predatory gamete.
  • @anavii12
    I'm here from Hank's tiktok video because I want to be part of the 2%
  • @danyalovich1934
    The fact that viruses exist in such numbers and for so long, means that they are essential and have a reason to be here and apparently everywhere. Rarely have we found that something that is everywhere is not an integral part of nature. Understanding their significance, function and evolution is going to be important to everyone.
  • @ruben77
    I remember reading something very like this problem of getting rid of all viruses in 1969's "The Andromeda Strain" by Michael Crichton.
  • @Thunderwalker87
    This hypothetical wish reminds me of the worst parts of my parents... they get a bad idea in their head and they will keep at it for a long time not getting how it will impact other things... then get angry when they finally get what they wanted and its impacts are worse than anyone could of ever imagined.
