Imagine this: back in 1985, a supercomputer called the Cray-2 was the fastest machine around. It could perform 1. 9 billion calculations per second, which is super impressive for its time. But here’s the kicker: it cost a whopping $44 million! Around the same time, another powerful computer, the Cray X-MP/48, was working its magic in California. It could do 400 million calculations per second and cost about $15 million.

Now, let’s fast-forward to today. You know those smartphones everyone has? They’re way more powerful than those old supercomputers. For example, an iPhone 15 Pro can handle 5. 6 trillion calculations per second. That’s like 3, 000 times more powerful than the Cray-2!

These old supercomputers were huge, expensive, and used a lot of energy. But they played a big role in science, engineering, and even movies. They had special cooling systems and were made for special tasks.

Then came the smartphone revolution. Today’s smartphones are small, affordable, and available to billions of people. They let us do amazing things like video calls, play games, and use advanced AI. This shift shows how technology has become more accessible.

But there are challenges too. We need to think about things like ethics, the environment, and privacy as computing power grows.

Looking back, it’s crazy to think how far we’ve come. The supercomputers of the 1980s were for a few, but now powerful computing is in everyone’s pocket. What will the next 40 years bring? Maybe quantum computing will change everything, or AI will push even further. One thing’s clear: we’re in an era of constant innovation.
