Lisp, C and Unix are over 40 years old

Hardware has improved immensely over the past 40 years, but software has barely advanced since the early 70s. What gives?

I have no idea what you mean, but CS has advance so much, there's an AI built that programs, and keeps optimizing it's programs, built on a lisp dialect, I forgot the sources for.

There's also advancements in OCR, to the point robots can learn from images.
