There is some truth to this - but there could still be hope for new UIs - even short of a direct neural interface ;-) The dominant GUI of today (still) relies on the desktop metaphor. The power of this was to take something known to us and expand on it. While there are a number of well documented flaws to this way of thinking a GUI it certainly has it's merits. But the key to radically better UIs does not necessarily lie in creating better version of this. The next-generation UI could be based on something even more familiar to us than the desktop. Our body (when functioning correctly) could be considered the ultimate UI between our brain and the world. This means that we already know a lot of things. F.instance, the existence of four dimensions (space+time) is so deeply rooted in our consciousness that we take it for granted. Don't want to go on about this for too long but it seems there is a lot to be won by working on creating UIs that seem "natural" to the way we act and perceive our world.
