Only thing this is not water, is a virus, and your metaphor doesn't accurately describe the situation. Once the virus is endemic, your "gates" are irrelevant, the only thing that can make any real difference is people's ability to swim.

I don't get it. COVID is already everywhere, what are we trying to keep outside? a potential new mutation that might happen? South Africa warned the world about Omicron lightning fast, travel got restricted and, anyway, Omicron got worldwide. All of this is just politicians looking for a free minute on TV. If you're worried about COVID, just book a booster shot if you haven't already.

Using the devices your organization gives you for personal stuff is both a security risk for them and privacy risk for you. I find surprising this simple facts are still largely ignored.

I know this times invite to freak out, by this things happens constantly and every nation with an decent army do it. A country sends a random military thing in route to a neighbour, which sends something to intercept heading, the response time gets timed and the military thing backs home.

Zero COVID policy worked like a charm at the beginning, but now doesn't make any sense. China has the vaccine for years but COVID is still a problem there. At some point they lost the way big time.
