A few years into this century, there was a time when people said, 'IT is over.

I was doing network research then and thought, 'There is nothing more to do in IT.

The reason is that the network, which was little more than a garden watering hose, has been replaced by a network that looks like a giant tunnel. And not only at work but also at home.

Until then, I had been struggling to "mediate water disputes" (QoS control of the network); however, I felt foolish.

I will never forget the feeling of emptiness I had at that time.

I had a vague idea that bio- and clean energy would become the mainstream in the future.

Well, I was one of the few wizards who could handle the control system spell language (C/C++), so I thought I could make a living for the time being by doing maintenance work on the remaining equipment from the previous generation.

And now, it's not finished at all -- or rather, it's being rebooted.

Thinking about where the conversion point was, I guess it would be the "cloud."

Then came the DX, and other things like "Raspy" appeared on the edge side.

The deciding factor was the "Generative AI" -- the impact was immense.

At a recent meeting, I was asked what I did for a living, to which I replied, "I'm an IT engineer," he replied, "Wow, that's great."

At that moment, I felt a little dizzy.

It was like being forced back in time to "a time when people were unjustly respected just for using computers."
