Nothing to do with accepting the limits. The point is that to overcome them you can't ignore them. Overcoming them is the craft that makes good new art possible. If you disagree with me deal with the point directly rather than misrepresenting it when talking to someone else.
When you tell a scanner to point to half way along the X axis to the left, you are telling it a direction, a relative distance, and assuming it knows where full scale is. How well it obeys is down to the scan system, but telling it where to plot the point is a simple value statement, literally equivalent to a number. Analog, digital, it doesn't matter, so long as that simple instruction IS that simple. This is why I argue against extending vector language into the scan system. All the scan system needs to do is make the move as fast and accurately as possible while protecting its own hardware. If it's this way (and it always has been, pretty much, despite the vast increase in scan speeds) then it doesn't matter what controller gives the marching orders, and that's the way it ought to be if we want choice in those.
Not one of my arguments is intended to limit progress, quite the reverse, and you'll never understand anything I say if you can't see at least that much.
