So what you’re essentially saying here is that now we having invented the ‘traditional’ computing system of a mouse, a keyboard, a monitor (and upgradable parts, for some reason), no other thing can exist to create or design things on?
You can’t see, in the near future, a (likely more powerful, much bigger), iPad type touch first, stylus, mouse, keyboard system? I mean, that’s the same as your so called traditional computing system, only with the ability to draw on it.
By the way, you can- of course- design things on an iPad. Plenty of people do. Perhaps you still need traditional computers in the workflow - but as I mentioned previously, the idea of the iPad as a serious computer has only just come about, realistically, in the past year.
