The first semester of my sophomore year, I took CS 337: Theory in Programming Practice from Jaydev Misra. On the last day of class, he talked about computer science in general, took questions, and let us out early. And on thing he said really made an impression on me. I’m quoting from what I remember today, I didn’t write the exact quote down, so this could very well be embellished or incorrect in some detail,
Even if we had the fast computers we have today in the 1960’s, and even if we had the internet, we could not have built a modern web-browser, because we did not understand enough about building programs of that complexity.
It’s amazing how young software development is as a discipline.
