40years

说明：  软件工程这个学科还很年轻，Peter Naur和Brian Randell今天依然健在。作为著名的编程语言归约BNF范式中的N，Peter Naur因设计和定义了ALGOL 60而在2005年获得图灵奖。因IBM System360的工作于1999年获得图灵奖的Fred Brooks在《人月神话》的结尾比较了化学工程和软件工程。他认为：软件系统可能是人类所创造的最错综复杂的事物，软件工程还很年轻，需要继续探索和尝试。
(Software Engineering in this subject is still very young, Peter Naur and Brian Randell is still alive today. As a well-known programming language paradigm BNF reduction of N, Peter Naur due to the design and definition of the ALGOL 60 in the Turing Award in 2005. IBM System360 due to the work of the Turing Award in 1999 in the Fred Brooks " The Mythical Man-Month" at the end of the comparison of chemical engineering and software engineering. He believes that: the software system may be created by human beings the most complicated things, software engineering is still very young, need to continue to explore and try.)
