While there isn’t too much clamorous mainstream debate about the current strain (SARS-CoV-2), the first SARS escaped the lab several times:

“SARS has not re-emerged naturally, but there have been six escapes from virology labs: one each in Singapore and Taiwan, and four separate escapes at the same laboratory in Beijing.”

Good grief. The contention here is that in 1977 the Russians were culturing samples of an existing strain of H1N1 that was known to researchers from an outbreak 26 years previous, but which had dropped out of circulation. And they oopsed, and it got out. That seems not totally improbable, and I'll believe the sequencing results.

I don't know how you get from there to (sigh) "Covid is human-engineered", at all. Can you explain how this is relevant at all, except in the way both hypotheses invoke evil foreign laboratories in totalitarian states?

I think there is enough evidence to suggest the possibility of a human role, but given the fact that a much more virulent virus could easily have been made I think if there was a human role it was an accident.

That and the fact that this harmed China both economically and in terms of reputation. Biological warfare is like using a grenade as a handgun. Yes it will harm the enemy, but...

Every expert I've read about thinks the "evidence" is too flimsy to even consider Covid19 being man-made. That post isn't interesting at all. It's just clickbait fodder that appeals to smart people who like to think they've figured shit out as opposed to the experts, even if it's a field that's totally outside their wheelhouse.
