Think that article you linked is basically saying the Coronavirus was created in a lab
There are a bunch of coronaviruses we know about. Some of them have existed in human populations for a long time, they are some of the viruses that are responsible for 'the common cold'.They were studied a bit, but were not much of a priority.
Then in 2003 the SARS outbreak happened, and then later the MERS. These are also coronaviruses, but with more serious implications for human health, so research and experimentation in this area picked up massively.
It is not in dispute that various labs have worked with various coronaviruses for years, including experiments where the coronavirus was altered in some way.
Nor would I dispute that lab accidents can happen. I have mentioned before that the 1977 H1N1 flu pandemic points in the direction of a lab release. The main indicator of that possibility involved various clues specific to that particular strain of flu at that time. It was so similar to a 1950 sample that was used in labs, that the possibility seemed more plausible than the other, natural possibilities.
But for theories about Covid-19 coming from a lab to gain any merit, they have to demonstrate something similar, or some other conclusive revelation has to emerge. I cannot completely exclude the possibility, but I'm pretty sure I can exclude all the people quacking about it right now because they dont have the evidence of that at all. Mostly they have the same thing that many theories have, which is just wide-eyed disbelief upon discovering something about the way the world already worked, that was already publicly acknowledged long ago, and then making a huge leap while sloppily joining dots. That sort of dot joining is usually rubbish, and when the dots consist of extremely technical papers and data, I expect to see plenty of unscientific humbug and conclusions that are well wide of the mark. I keep an open mind to the actual possibilities, but not the narratives built on imagined smoking guns that are nothing of the sort.
