The context of 'Matters' in this case is as an important part of the industry. Fortran and Cobol are still extremely heavily used on the servers of many slow moving institutions (banks and the like). Regardless of how many cpu cycles they consume they don't matter in the field of software development. Some low level tech will always be in the stack, but it doesn't mean it's an important part of the field. It will be relegated to a critical yet niche area of programming.
