I lived through the First Cold War. I was born 9 days after the Berlin Wall was put up. I was a year old when the Cuban crisis erupted.
In school, we learned how to put on a gas mask and where the nearest nuclear shelter was.

State of the War in Iran
Is Israel Running Out of Steam? The US is bleeding cash. Threats to raise oil prices (even more). A new participant in the war? Dark Omens. And, fake numbers?

TL&DR: Very positive.
Takes some time to get used to, but not needing to struggle with code is brilliant.
Expensive in terms of usage on my PRO plan.

But this article does a great job of explaining the economic costs.

Measles outbreaks are costing the U.S. millions of dollars. The true losses can't be counted.
As vaccination rates decline, the economic consequences will increase, research suggests.
