lan Turing is widely considered to be the father of computer science in many ways. In a nutshell, Turing laid the foundations of computer science in the 30s and 40s, for the future to build upon. He did this by doing a lot of work with artificial intelligence, and formalizing the idea of an algorithm, something which is absolutely integral to computer science as we know it.
And they have. It’s 59 years after he died, and since then computer scientists have developed new concepts such as object-oriented programming, which most large-scale programs today use. But even that’s an old concept, having gotten popular in the 80s and 90s.
Now it’s your turn to develop the next big CS concepts, or at least work with those new concepts as you code on the technological frontier. As computers get more and more powerful, the need for equally powerful programmers gets even bigger.
If you like solving tough problems methodically and tenaciously, and like puzzles or systems or patterns, consider taking an intro to CS class your freshman year. If you like it, consider making it your major.
