That's a ridiculous dismissal to make; we live in a world where hand-written assembly is considered a badge of honor, where people prefer to patch up a 40-year-old dinosaur rather than make something new, where people to go ridiculous lengths to avoid using a mouse simply because Unix didn't have mouse support in 1973. Is it any wonder that we're not using anything better?

Even in video games where this held true for longer, this is generally no longer the case.

Also not true, Generally engineers prefer to make new things, The problem is that, creating new products from scratch to replace old ones ends up almost always being more effort than expected. Failure, is what causes patching the dinosaur the better approach, rather then engineering desires, Netscape is a classic example.

I don't know what world you live in, because in the world I live in, computers with mice are much more popular than the alternative.
The fact that none of these systems are in usage is true, you can make excuses for them, but the fact of the matter is that there is a lot of smart people trying, and very little success. There is little evidence to support that this is a superior approach.
