It might have surpassed 2009 swine flu (although back then people who died with it weren't counted as dying of it, and also nursing homes weren't forced to house contagious patients). It is my understanding that it is a lot less deadly than
1957-58 Asian Flu: "Approximately 1.1 million people died worldwide, according to the CDC; of those deaths, 116,000 were in the US. Most of the cases affected young children, the elderly and pregnant women."
Note, that back then they weren't inflating the numbers like they do now, and also back in 1957 the world population was 2.9 billion, which is 37% or about a third of what the world population is now. that means that the mortality per million of population was 2.7 times the death toll. To match that mortality, we would need about 3 million people to die worldwide.
The flu this year is also less deadly than 1968 "Hong Kong Flu" Pandemic. My mom caught the flu back in 1969 and came close to death.
"It started in 1968 and lasted until 1969-70. The virus responsible for the pandemic is believed to have evolved from the strain of influenza that caused the 1957 pandemic through "antigenic shift" — an abrupt, major change in the virus that results in new surface proteins, creating a virus subtype that humans have little or no immunity to because the body doesn't recognize its surface proteins. According to the CDC, approximately 1 million people around the world died from this pandemic"

The population back in 1968 was 3.5 billion, which is 44% of today's population. To reach the same mortality rate per million of population, a flu would have to kill 2.2 million people worldwide.
So it isn't nearly as deadly, yet back then nobody has even considered lockdowns, and I am pretty sure that back in 1957 and 1968 most people weren't even aware of those pandemics.
People carry on as if this were something like the Spanish flu. Back in 1918, it killed between 50 and 100 million people. The world population in 1919 was 1.8 billion, 23% of what it is now. So to match the rate of mortality, 2020 flu has to kill at least 50 million times 7.8/1.8 = about 220 MILLION people (over 400 million, if we go with the upper estimate of 100 million). So what we have (despite all of the overestimation going on) is more than 200 times (or even more than 400 times!) Less deadly than the Spanish Flu of 1918...
