I find it really fascinating how computing became a phenomenon during the Vietnam War and Cold War. The area of spending was mostly put towards computers, especially since digital computers replaced analogue computers. These computers were made with vacuum tubes and when you had to replace a bad tube, someone had to check the 19,000 different possibilities. Wouldn’t you love to have that job? It must have taken forever to find the right tube. It’s really interesting how dependent people became on these computers, and here we are today in the modern world, still very dependent on computers. The evolution of computers is an interesting topic and it was intriguing to learn how they transitioned from analogue to digital.
