So, I was recently pointed to Steve Jobs’ NeXTSTEP Release 3 demo. It’s pretty amazing to watch what would eventually become OS X in its first incarnation. What’s more amazing is how much of that framework still exists today. In fact, it almost makes you wonder what they have been doing with OS X since so much of it was obviously functional in the early 90s.

NeXTSTEP’s code is still seen today in OS X – if you poke around in the code or even some little hacks from the command like, you’ll still see objects referred to with their original “NS_” prefixes.

Anyway, check out the video. It’s long, but it’s really interesting.
