Which is a terrible analogy because people still use desktops.
Steve never said that PCs would go away. He simply believed that they would end up getting used less and tablets became more capable and convenient and more computing tasks were performed on them as opposed to on a PC.
And in a sense, Steve wasn't wrong. I use desktops too. They aren't sexy, but they get the heavy lifting done, and they are never leaving my house. But if I want to do something like reply to an email, I would sooner reach for my tablet than switch on my iMac, because the former is just more accessible.
Research before you reply. App developers can't fix an iOS limitation.
App developers can get creative and try to work around that issue though.
For example, a new app called Sidefari uses safari-view-controller to simulate having a 2nd Safari page in split-screen mode. Clipboard-management apps like Clips offer a workaround around the limited clipboard function in iOS by streamlining the saving of copied text to the app, letting you copy and paste multiple text snippets easily via a 3rd-party keyboard.
Perhaps there is a way to simulate VNC functionality without actually having to VNC in itself?
