Corona virus, China major city lockdowns, etc.

It is also an example of the Gambler's fallacy.

No it wasn't. At no point did I try to link the timing of the next pandemic to the recency of this one. I merely pointed out the frequency of pandemics is rare: roughly once per hundred years based on available data. Extrapolating from that the median average indicates that, at any point in time, you should plan for a pandemic in roughly 50 years time but with a high degree of uncertainty (basically, no certainty at all).

A hundred years ago you couldn't go just about anywhere in the world in twenty-four hours. There are literally billions of more people now than then

That's true but hand in hand with that comes a greater understanding of pandemic spread, both on a personal and societal level, and a greatly increased ability to treat pandemics when they arise. None of us can know but I'm I'm assuming that these factors roughly cancel each other out.

how can anyone profit if mankind is destroyed

They can sure make a bundle while it's all burning down. I honestly don't feel that's what's going on with Corona though. I think the pharmaceutical companies have actually taken their social responsibilities very seriously on this and I take my hat off to them for it. (I doubt it'll stop them fleecing us for all we're worth once this is over though)
