If a person from 30 years ago suddenly arrived today, they would probably be stunned at first.

Back then, there were no smartphones, no short videos, no food delivery, no mobile payments. Many people didn't even have a phone installed.
Communication relied on writing letters, researching by flipping through books. News traveled slowly, and life moved at a slower pace.
The amount of information an ordinary person could access was actually very limited. Many knowledge areas hadn't changed much over several years or even decades.
But in just 30 years,
Humanity has gone from information scarcity to information explosion.
From waiting for news to being chased by messages.
From taking days to send a letter to sending a message that reaches the other side of the world in seconds.
In the past, people feared not having news; now, people fear having too much news.
And this is the most frightening part.
30 years may not be long in history,
but in an ordinary person's life, it's enough to change the entire operating system of the world.
Many people think there's still plenty of time for the future.
But that's not necessarily true.
Looking back from 30 years later, the things we take for granted today might seem as slow and clumsy as writing letters and flipping through yellow pages did back then.
It's not that the times are changing quickly,
it's that people haven't yet reacted, and the next wave has already begun.
