You are not wrong. Remember you will have a forty-year long career and technologies will come and go. Get a good foundation and you'll be able to do anything you want. https://en.wikipedia.org/wiki/The_C_Programming_Language https://en.wikipedia.org/wiki/The_C_Programming_Language is still a good book and it's 40 years old.
