I have often heard Turing machine this and Turing machine
that. It’s only lately that I’ve actually read about the concept and come to
understand that one aspect of Turning machine is that it aspires to be
universal, capable of simulating other, more specialized machines.
So now I’m seeing them everywhere. My iphone is a Turing machine, the laptop I’m writing this on, the ipad I’m looking forward to buying. All of these devices are wireless receivers, can record text, etc. Devices today have different strengths: a high end digital SLR can take video and has built-in GPS, but it’s best at taking digital photographs. I can read the New York Times on my iphone, but like it better on my laptop, and will probably like it best of all on an ipad.
Still, it was a breakthrough for me to realize the emerging trend isn’t toward one master device that does everything, but toward many devices that do all sorts of things.
Philosophically, what’s so damn interesting about this is that the machine, the poster child for determinacy in an earlier, clockwork age, now has poster children all over the place for indeterminacy. A Turing machine is, by definition, indeterminate.
If Gilbert Simondon is correct, most machines are similarly indeterminate. Only we restrict their functions (fruitfully) to limited tasks. This is one reason why, predictably enough, Deleuze and Guattari are so enthused about Simondon. Even non-Turing machines have an underlying diversity or flow that can be rechanneled in unexpected ways. Think, for example of how bicycles have mutated and diversified over the last forty years: road bikes, fixed gear, mountain, BMX, stunt, commuter, cruiser, exercise, rickshaw taxi, power generator. I could go on, but you get the point. The underlying technology is less determinate than I’ve been accustomed to think of it.
Got much more thinking to do about this, but it’s a start.
