I'm estimating 7 millions of deaths, so it's definitively not good news. The 10% is only for people that is old or have previous respiratory problems, and it's hopefully inflated because mostly only the people with strong symptoms get tested.
Hopefully we can make some measures to reduce the number of death, specially when the hospital are expecting a big spike of case instead of a surprise.
Anyway, in a year this will be old news, and in 10-20 years we will probably have another similar pandemic.
