Yet more on separating artificial from actual intelligence.

Depths of Design: Moving Pixels


Editor’s note: This is Part II of a series. Look here for Part I. Cross-posted from Mind Matters News.

As with traditional art, computer animation has followed a similar trajectory toward realism. Early animations were as crude as rock carvings, limited as they were by relatively weak CPU’s, as yet undeveloped rendering engines, and a lack of digital artists. The monochromatic Space Invaders was endlessly playable, as were the whirling, 8-bit dervishes of Centipede and the bubble-gumless, three-dimensional spaces of Duke Nukem. But the graphics were a million pixels from virtual reality.
         Now decades and countless iterations in, with enormous human capital and ingenuity invested in motion graphics and GPUs, the optics are indeed seductive, convincing, and engrossing. Head phones on and eyes glued to the screen, it’s easy to get lost in the sprawling world and epic narrative of Mass Effect, or to feel that you are attacking the Ludendorff Bridge at Remagen with an M1 Garand rifle, your rag-tag squad assisting. With each iteration, game developers make strides in simulating the unique recoil of each gun model, the aural pattern of explosions near versus far, the game physics of spilt blood and bent grass underfoot, and the fraying edges of a soldier’s ribbon bars, specific to rank and nation.
           
Bravo! Charlie!

It’s amazing. It’s an adrenaline rush. And it’s all artifice. These animations are becoming ever more realistic, but not in the least bit more the kind of real thing which they represent.

In addition to cosmetic advances, motion capture technology has progressed by leaps and bounds. Painstaking attention to plotting our distinctive expressions and gaits has greatly increased the appearance of natural movement. Ever since Andy Serkis so convincingly gave life to Gollum, recordings of humans in motion have supplied the scaffolding for countless characters. 
                  In animation … everything is fabricated. … Every moment. Every scratch and look. Everything is a discussion. There are no gifts. There are no happy accidents … It was useful having the live action performance reference. We’d pull them up in front of the animators and say, look at what’s happening here. Little twitches underneath the eyelid, little things that are involuntary became very important.

GORE VERBINSKI, “RANGO BEHIND THE SCENES: BREAKING THE RULES”
                One of the joys as a viewer is having that dawning recognition of a familiar actor who has been reincarnated as Puss in Boots, Shrek the ogre, or Mator the tow truck. The idiosyncrasies and tics of the human originals are prized source material for the animators. So, Kristen Bell’s signature phrase — “Wait, what?” — and her habit of biting her lip is mirrored in Anna of Arendelle. Dwayne “The Rock” Johnson’s brow wave personalizes Maui. Although these beloved characters are singing and dancing and joking along, like Mona Lisa, the image is a mirror image. It has no life of its own. 
                
No Breaths, No Sacrifices

Though we are moved by these pixels on the screen, our digital allies and enemies breathe no breaths, make no sacrifices, feel no lonely deaths. Whether crying, dying, or respawning, they are as lifeless as a dead pixel and vacuous as a wireframe.
               Because the textures that skin them and algorithms that animate them are more sophisticated, it is tempting to think that the ducking and evading Juvies, Pouncers, and Swarmaks of Gears of War are more intelligent than Pac Man’s nemeses: Blinky, Pinky, Inky, and Clyde. One might think that whereas the ghosts that haunted Pac Man had a wisp of personality, the villainous grunts of a modern first-person shooter have a measure more. Surely, in some future game, they’ll reach self-realization. Game AI will continue on this trajectory and surpass human intelligence, just as Watson bested Kasparov. But the truth is, none of these avatars possess any inherent intelligence whatsoever. Every human instinct therein is an extension of a game developer’s forethought. The characters are thoughtless.

We’ve erected this elaborate system of gears and pulleys using electronic nodes. The number of these levers that we can fit on a circuit is mind boggling. At the push of a button and the tilt of a joystick, these systems are able to reenact remarkable routines that the human programmers have strung together. But as the less exhaustively routinized NPCs (Non-Playable Characters) in the game betray, if the programmer hasn’t yet written the routine, the character will be left kicking blindly into a wall.

Photosynthesis and Darwinism's quest for a simple beginning

 Brand new study on the evolution of photosynthesis.


How exactly is evolution a fact when, as the number two science journal in the world put it, “How and when Cyanobacteria evolved the ability to produce oxygen through photosynthesis is poorly understood”? Or as evolutionist Robert Blankenship admitted, “The whole question of the origin of cyanobacteria has long been a mystery because they kind of just appeared out of the tree of life with this very advanced capability to do oxygenic photosynthesis without any apparent forebears.”

If the cyanobacteria that do photosynthesis “just appeared” with this “very advanced capability” and “without any apparent forebears,” and if how and when they evolved photosynthesis “is poorly understood,” then just how is it that evolutionists are so certain that evolution is a fact?

What am I missing here?

It is not as though photosynthesis is a tangential capability or a minor event in the so-called “evolutionary history” of life. As the leading science writer Charles Q. Choi put it, “One of the most pivotal moments in Earth’s history was the evolution of the photosynthetic life that suffused air with the oxygen on which virtually all complex life on the planet now depends.”

Nor is it as though photosynthesis is a simple capability, in no need of explanation for how it possibly could have arisen by random mutations. Anyone who has studied photosynthesis even superficially knows it is incredibly complex. And for those who have studied in greater detail, it only gets worse. The molecular machines and their exquisite, finely-tuned, functions are truly amazing. It doesn’t “just happen.”

Even evolutionists, who are always trying to explain how easy it would be for biology’s wonders to arise by happenstance, admit to the complexity of photosynthesis. As Blankenship put it, photosynthesis is a “very advanced capability.” Similarly, Woodward Fischer agreed that the evolution of photosynthesis would be “very challenging”:
            It took a substantial unfolding of evolutionary time before oxygenic photosynthesis developed, perhaps because, as we know, it was a very challenging biochemistry to develop.
                      Nor is it as though the evidence we do have suggests any kind of a straightforward evolutionary development of photosynthesis.

If evolution is true, then we must fire up fresh rounds of evolution’s fake news, including incredible convergences and massive horizontal, or lateral, gene transfer and fusion. Round up the usual suspects:
             The phylogenetic relationships of these prokaryotes suggest that the evolution of aerobic respiration likely occurred multiple times. This, along with evidence that the modern photosynthetic system apparently arose through the lateral gene transfer and fusion of two photosynthetic systems
                            This is absurd. Convergence, horizontal gene transfer, and fusion are all made up mechanisms to fix the problem that the scientific evidence contradicts evolutionary theory. This isn’t making sense.

But it gets worse.

Not only are evolutionists forced to draw from their army of phony explanatory mechanisms, but they are left with the proverbial “missing link.” The problem is, from where did the photosynthesis come? It couldn’t have come from the purported common ancestor via descent, and it “just appeared” with this “very advanced capability.” So evolutionists have to usher in their horizontal gene transfer story.

But from where?

From where did the incredible battery of genes—that would just happen to team up and create the all-time incredible capability of photosynthesis—come? Conveniently for evolutionists—and here’s one of the beauties of being an evolutionist—they can never know. Like Flew’s gardener, evolutionists are certain that some “missing link” organism somehow had photosynthesis up and running, or just happened to have the crucial genes just lying around, but we likely will never observe that organism because it has long since become extinct.

Oh how convenient. Some mysterious organism did it. We’ll never know just how photosynthesis evolved because the organism where it happened has long since gone extinct, billions of years ago. Since then, it just luckily passed the technology around for other organisms to have, such as the cyanobacteria. Choi and Fischer explain:
                   The fact that Oxyphotobacteria possess the complex apparatus for oxygenic photosynthesis while their closest relatives do not suggests that Oxyphotobacteria may have imported the genes for photosynthesis from another organism via a process known as lateral gene transfer. It remains a mystery what the source of these genes was, “and because it happened long ago, it's pretty likely that the group may actually have gone extinct,” Fischer said.
             Can I be an evolutionist too?

Photosynthesis is crucial to life and incredibly complex, evolutionists haven’t a clue how it could have evolved, it doesn’t fit the evolutionary common descent model and “just appeared” without a hint of where it came from, evolutionists are forced to make up a long just-so story to try to explain it, their story can’t be falsified because the origin of photosynthesis has long since disappeared, and on top of all this, evolutionists insist their theory is a fact, beyond all reasonable doubt.

This is hilarious. It is like something out of a Monte Python skit. Evolution loses every battle, but manages to win the war because, after all, it’s right.
