I stopped taking this guy seriously after he proposed "just" digging canals to bring desalinated ocean water into the U.S. desert.
The problem wasn't the mortality rate, it's the fact that the media can cleverly turn something in a huge deal by talking endlessly about it. During COVID, there was no other news except the virus on news for 24/7.
Most people realize this is hyperbolic rhetorical. Taken in context (instead of nitpicking a minor "detail") he's calling attention to the fact some people think that AI will affect EVERYONE negatively.
This article was not about Covid, which means his sarcastic question serves a purpose to illuminate the issue with judgment on the rise of AI, not argue that "only a million people died" as you claim.
