The history of Unix-like systems dates back to 1978 with the development of BSD Unix. In 1987, Andrew Tanenbaum began work on MINIX, which served as a reference for Linus Torvalds when he started developing the Linux kernel in 1991.
Microsoft began developing MS-DOS in 1981, with the project running until 1993. The Windows operating system project was launched in 1985. These systems followed a different development path compared to the Unix-based architecture.
The author notes that the cost of redeveloping Linux-based systems is reported to increase by hundreds of millions of USD in various studies. The text suggests that writing new code from scratch might be more efficient than maintaining the existing legacy structure.
