Maybe with the power of a supercomputer, Mathematica can finally launch in less than 30s. I have no idea how a software that still does essentially the same thing as it did in 1988 can be that sluggish.

I think it's an extreme example of not-invented-here syndrome. In many ways that leads to interesting novelties, and in others it leads to not having undo/redo until the 2010s.
