-- How a scientist could make so brave conclusion about the way the control unit of the hand that direct the mouse works/i.e. the brain/, just by that the trajectory of the mouse is not straight, and the trajectory is been corrected in "run time"?
And more - it's easier and more natural for the hand to move in arcs rather than in perfect straight "rails", because the way it's constructed, not the way it's controlled.
You can move the hand in almost straight lines, but this is taugh to perform and rarely performed, because control is harder, and because the arcs does the job.

What a brilliant invention! It sounds like the control unit could try to work out and "make profit" of the first came parts of an input which comes from serial input stream, before the entire message -- whose lentght, also, is usually unkwnown -- enter the memory. That doesn't prove that the mind doesn't understand the input that is came in discrete stages, when it finds some kind or a new kind of meaning in the input came after a revision.

Computers, seen in execution, are dynamical systems, and they are "gray" if we look at more than one bit of their state definition.

Brain is not -- brain design is in the DNA. To change the brain, you must change the DNA and wait the brain to grow up.
-- They mess MIND with BRAIN
The article compares MIND (abstract high-level system containing a lot of parts) with the Digital computers, seen as "ones and zeroes" (the lowest level of abstraction, the simplest element of the machine -- it has zillions such elements). With enough digital elements, ordered complex enough, and with an analogous output device with enough differentiable states (such like a hand that moves a mouse), you can model any "smooth" or non-linear transition and trajectory - you just need a Digital to Analog Convertion to show the "smoothness" more clear to who don't believe you. The smooth trajectory of hand does not imply neither that an analogous device controls it, nor that that control device works "not on discreete steps" inside, in the conceptual structure of their "processors".
I'll recall again that the accessible coordinate system of hand is not Cartesian, and non-linear motion is not implied directly fron the control unit, but more from the controlled unit.
