Unless someone has the antidote, this seems like a really counterproductive bio-weapon. Whoever created this needs to be put up against the wall.
1) It mutates into a form no more dangerous than ordinary flu. This is how the 1918 Spanish Flu ended around a year after its first major spread across America. That is less likely for CoVid-19 because it seems less virulent, and is much less lethal, than the 1918 Flu, though a mutation ending will still happen eventually, just not so soon.
2) A successful treatment is found. See:

and
https://www.en.etemaaddaily.com/world/international/china-starts-clinical-trial-for-remdesivir-medicine-in-coronavirus-treatment:70811
for an example of possible success and an ongoing clinical trial. The successful use of remdesivir occured in January and the Chinese clinical trial began a few weeks ago. We might have results from the clinical trial by July or so. If it is successful, it will take months more to get enough production going to make more than a minor difference in treatment, i.e., mass use of remdesivir, if it works, probably won’t happen any earlier than December of this year. And some other successful treatment might come along but will be subject to the same delays in use.
3) A successful vaccine is found and deployed en masse. The generally agreed period for this is 18-30 months for development of a vaccine and another six months to produce hundreds of millions of doses and deliver them to the public.
Rated by how quickly the pandemic might end, it's successful treatment first, then mutation and finally a vaccine.
"Here's the Q. If you don't build immunity (do you?) and it doesn't peter out--does it just keep violently circulating and you keep catching it until you can no longer put up a good fight?Unless someone has the antidote, this seems like a really counterproductive bio-weapon. Whoever created this needs to be put up against the wall."
