The other day, some persons now keep talking big about the future technology, thought they had told us about the wrong predict of "GUI ruin".

When the object oriented language became a trend twenty years ago, they had burned FORTRAN and COBOL in effigy with saying

"Like that dirty languages are going to be ruined."

According to ITR report, the use of COBOL is the third after Java and Visual Basic

According to IPA report, the existing COBOL code is 16.8% after Java (25.4%).

According to Gartner report, the code is increasing five billions every year, and the ratio of code make up 65%, two hundred billion of all code of three hundred ten billion

Though I know well any result of research is controllable from methods and views.

It's an indisputable fact that the ruin is out of question.

-----

Even if in FORTRAN or COBOL, the legacy of the past (library group), would be enormous quantity. In addition, the experiences in use over several decades are credible.

At the time, we engineer, thoroughly had neglected to this idea "Heritage (Legacy)".

In the world of computer software, a lot of innovative technologies have happened, but we finally couldn't cull this overwhelming "heritage" eventually.

-----

In other words, just say, "Old" in itself (is suppose to) has a huge value than the "New".

At first glance, senior engineers look like to be daydreaming and useless for everything but they have accumulated (Legacy) great assets.

Mr. /Ms. young engineers. Do you understand?

If you make fun of them, you could encounter dangerous situations.

If they go all out, they use technical legacy skills, abuse the power of unreasonable positions, in addition to,

make you land in hell.
