If part of the new normal is that everybody works from home unless it's impossible, I think that's a good thing. It's what we should have been doing ever since the technology became available, ie ages ago.
Never is a long time. Those with a natural immunity will pass it on to future generations. And even if it mutates in order to stick around, it'll just be another infection amongst many others that species have to cope with. Then when genetic science/engineering has matured these things may not be much of an issue any more. Meanwhile the percentage of us expected to get it and survive will hopefully give us this herd immunity they talk about.
I think one can have expertise in the field of virology, and if you have also taken an interest in studying this particular one from the start you can be considered an expert on it. Surely the way epidemics and pandemics progress must be known.
I think they called Dr Fauci an expert as he is an immunologist. I don't think there are any experts in this yet.
Medical staff all around the world are gaining on the spot experience every day and what techniques can help or not. All patients are guinea pigs (if it's ok to use that term) in this viral war.
