If kids get accustomed to using Java, or Linux, or Perl, Python, Ruby, PHP, Node.js, Lisp, Scheme, Rust, D, FreeBSD, Haiko OS, GNU Hurd, then no corporation is locked in to profit from it. How much money does Red Hat get from most Linux users? None. How much money does Oracle get from most Java users (much to their dismay)? None.
It sounds like we're close to the same age. I used Vax VMS in college, too. But all of my classmates outside the computer science department had to take at least one course on Microsoft Word and Powerpoint. Look where the world is now. And I can make Linux dance to my tune at the house, my kids have seen me use it since they were in diapers, and my oldest is twelve and he still prefers Windows because that's what he gets at school.
