I'm not personally worried, but today I cancelled my hotel reservation for RubyKaigi in April. Do I think I am going to get Corona Virus? No. It's very unlikely. Do I think I am going to catch Corona Virus at the conference? No. It's very unlikely. However large numbers means that the chance it happens to someone at some conference is incredibly likely. Indeed, there were just 8 cases in Hokkaido that seems to have originated from a trade conference. There is no real need for me to go to a conference. I can wait until next year. If we avoid unnecessary interactions in large numbers then it will make a difference. Some people need to meet, but I certainly don't need to get together with a whole bunch of strangers in a remote location to talk about Ruby, so I'm not going to.
