Text terminals are terrible for something I need to do every single day: Showing others what I am doing on the computer.
Without animations you are like a person with autism disorder: It works for you but nobody that is watching you can understand what you are doing, you are in your world. You do a key combination you know(but others do not) and the screen changes instantly.
Repeat this a few times and you have a lot of confused people in your audience.
I agree that we need everything: something extremely fast, intuitive while beautiful and useful and extremely easy(and cheap and fast) to program.
But nobody has done it because it is hard as playing violin to be able to design a simple design alone, let alone make it fast. In the real world you need to pick your priorities, to constantly triage and make decisions.
