I am very glad to have your consistent and impassioned reports to improve my understanding of our world. I rarely have commented on them, but do so now in order to prevent misunderstanding from resulting from this one inadvertantly.
At about 16:35 you mention that China is using an anti HIV drug against the Coronavirus, and you infer that this means they understand it has similarities to HIV that indicate it is a manmade virus. This is not factually correct because of the nature of viricides, and the difference between them and other biocides.
Virii are dramatically different from living things, and do not actually meet the definition of life. They don't eat, excrete, grow or respire. They're simply chunks of genetic material with a few tools that allow them to hijack living cells to reproduce themselves. Drugs which counter HIV therefore counter this ability all virii have to hijack cells. This is why an anti-HIV drug may be useful against every other virus. So, the use of an anti-HIV drug in no way implies knowledge of similarities between HIV and coronavirus due to their manmade nature. It's just that all virii do the same thing, and antiviral drugs can only act to prevent virii hijacking our DNA to replicate themselves.
Edit: it's possible that some of the parts of HIV that specific drugs impact are the 'tools' I mentioned, which are basically means of getting into cells, and which would be specific to HIV. In that case, drugs would be specific to HIV. Interestingly, due to the specific inclusion of HIV segments in nCoV that are those tools, it's possible HIV drugs that block those tools could in fact support your assumption.
We just don't have that information at present to confirm that.
Thanks!
Very good point: the common anti-AIDs drugs are also used against Herpes cold sores for example.
