I am currently writing a paper on a search report for the past 40 years or so on a technology, but it is a difficult task.

This is because old information is hard to come by.

For example, if I am trying to collect books from the 1990s, I will not find them in libraries.

Technology is constantly being updated, so it goes without saying that it is desirable to replace it with the latest books, but it is troubling to find research on the past.

"Historians are awesome"

I am impressed.

It is this difficult to go back just 40 years in the past. The difficulty of researching documents more than 10 times that long ago is unimaginable.

Not to mention the style of writing, the letters are different from the present.

In this case, recent character recognition technology has greatly improved the literacy rate of documents that are more than several hundred years old.

I am truly happy that the latest technology is unraveling old history.

It is a struggle for my research, but I feel fun to get a bird's eye view of how the world of technology is moving left and right with the trends.

It is because it is easy to know how researchers around the world are "chasing" their idols (the latest technological trend).

It is the "dancing buzzword".
