I'm not entirely sure why people are picking on this particular flu epidemic specifically as it's not exactly a plague-level epidemic and the casualty rate is extremely low by apocalyptic standards. Apart from the issue of too little capacity in hospitals and morgues, there's not really much that is threatening about this flu from a big-picture perspective.
It's sort-of a slightly worse version of the usual annual flu epidemics that we all live with all year every year. About 50,000 people a year die from normal flus, usually the old and sick. This one looks like it would do more than that, which makes it a bit more threatening, but, essentially, it's just another flu.
Nope. Let's do some numbers.
Ordinary flu has a reproduction rate of ~1.3, i.e. one infected person infects 1.3 others. Mortality is ~0.1%. Mathematically, the spread will stop when (1.3-1)/1.3 of the population have acquired herd immunity, i.e. 25%. In a country like the U.S., that's 75 million people, of which 0.1%, i.e. 75.000, will die. That's on the high side, but in the ballpark for an aggressive strain of flu, like in 2017/2018 (61.000 recorded deaths in the U.S.).
SARS-Cov-2 has a reproduction rate of ~3, mortality is estimated to be ~3%. Spread stops at (3-1)/3 = 2/3 of the population, that's 200 million in the U.S., of which 10% will need hospitalization (20 million), and 3% will die (6 million).
And if these 20 million need hospitalization at more or less the same time… well, tough luck, there will be no spare beds and respirators, so mortality will shoot up towards 10%.
The difference between 75.000 and 6 - 20 million is substantial enough not to trivialize this as a "bad flu". The population of RPGWatch, which has been established to consist mostly of octogenarians, has reason to be concerned. So hunker down at home and finally get to reading "A la recherche du temps perdu". Stretch the progression of the epidemic so hospitals operate within their limits and can give everyone good care to keep mortality down, and give researchers time to come up with a vaccine.
