I don't understand this sentence
"The process takes thousands of years. Humanity has lived through the shift multiple times."

No we have not. The last flip occurred 780,000 years ago. Homo sapiens did not exist then, we were Neanderthals or just homo erectus back then.

I think the author meant LIFE has survived through the shift multiple times, since there is no evidence linking magnetic reversals with extinction events.
