4K demos in DOS didn't look anything like these modern ones, they were much simpler. They were still very impressive for the time, but the grandparent-post's point is valid. If you wrote a 4K DOS demo today against modern hardware you wouldn't be able to reach anywhere near the look of these other demos which sit ontop of OpenGL/D3D/Win32 etc, because you'd need to build the equivalent of those API's functionalities into your demo.
