I have to concede that this should stand as a testament to the power of generative AI and what it allows ordinary developers to accomplish. It's hard to complain about "slop" when this guy magicked an 8086 graphical operating system out of the aether and then ported it to a number of different architectures, running efficiently in space and time on each.
If you still believe that writing software "by hand" isn't cooked, you haven't been paying attention.
