Approximately 3.5 million globally have died from covid according to the WHO: https://covid19.who.int/

If you include deaths from related factors, like increased poverty or unrest, I'm sure the numbers go up a bit, but not to tens of millions.

I don't state this as an attack, by the way. Covid and its entangled cultural and political issues are enormously emotionally charged, and, one way or another, that tends to skew our perception of even relatively simple facts.

One thing I think the Hacker News community does well, at least aspirationally, is try to keep sight of the fundamental technical details of issues. For a pandemic, having an accurate intuition of its scale falls into this category IMO.
