Wm. Dembski pre-empts aiguy
I will also refer you to page 90 of The Design Revolution by Wm. Dembski.
Once suitably programmed, the computer operates by necessity. Consequently, its outputs, when fed into the filter, will land at the necessity node of the filter.
Which pretty much sums up aiguy's argument. Then Wm. follows with:
But whence the computer that runs the program? And whence the program? All computer hardware and software in our ordinary experience is properly referred to not to necissity but to design.
And in the end aiguy still has some strange fixation with the word "intelligent". Unfortunately that may prevent him from ever understanding why his argument is bogus. You first have to understand what it is you are arguing against before you can mount a successful argument against it.
