Cyborg games

I hate computer games.

Now, don't get all up in arms.  I'm not saying you can't love them and want to spend all available waking hours playing them.  This has nothing to do with moralizing about productive use of time.  For me, computer games are the opposite of relaxing and entertaining, particularly the ones where speed is required.  Even simple ones like Tetris get me so wound up I want to scream.  I still recall vividly my one and only time playing Angry Birds, because I got way angrier than the birds were.  The third time I flew my Bird head-first into a steel pipe, I just about had to be physically restrained from throwing my computer out of the window.

I realize this is an admission of a mild psychiatric disorder.  It's just a game, nothing to take seriously, certainly nothing to get agitated about, and so forth ad nauseam.  But it's a purely spontaneous reaction that I seem to have zero control over.  The result is if I had to choose between spending an hour playing Super Mario Brothers and having my prostate examined by Edward Scissorhands, I'd have to think about it.

All of this comes up because of a preprint of a new scientific paper sent to me by a friend wherein some researchers apparently taught an "organoid" -- a small, organ-like structure made of cultured brain cells -- how to play Pong.


Here's how the authors, a team led by Brett Kagan of Cortical Labs of Melbourne, Australia, describe what they did:
Integrating neurons into digital systems to leverage their innate intelligence may enable performance infeasible with silicon alone, along with providing insight into the cellular origin of intelligence.  We developed DishBrain, a system which exhibits natural intelligence by harnessing the inherent adaptive computation of neurons in a structured environment.  In vitro neural networks from human or rodent origins, are integrated with in silico computing via high-density multielectrode array.  Through electrophysiological stimulation and recording, cultures were embedded in a simulated game-world, mimicking the arcade game ‘Pong’.  Applying a previously untestable theory of active inference via the Free Energy Principle, we found that learning was apparent within five minutes of real-time gameplay, not observed in control conditions.  Further experiments demonstrate the importance of closed-loop structured feedback in eliciting learning over time.  Cultures display the ability to self-organise in a goal-directed manner in response to sparse sensory information about the consequences of their actions.

"We think it's fair to call them cyborg brains," Kagan said, in an interview with New Scientist.

What's a little humbling is that these organoids probably play Pong better than I do.  And I doubt that after playing Pong for five minutes, they want to smash their Petri dish against the wall, which is how I'd react.

It does make me wonder where all this is going, however.  We have a clump of cultured brain cells integrated into electronic circuitry (thus the appellation "cyborg brains") that can learn, and get progressively better at, a game.  Okay, it may seem like a silly accomplishment; an organoid playing Pong, so what?  But keep in mind that this is only a proof-of-concept.  If the process works -- and it certainly seems like it did -- there's no reason they can't ramp up the sophistication of the task until they have something that is truly a complex synthesis of organic brain and electronic brain.

Just as long as we don't take the research too far.  Fellow Doctor Who fans know exactly where I'm going with this.


In this case, maybe the outcome would be that the Cybermen would do nothing worse than forcing humans to play hours and hours of Pong with them.  And I guess that's better than their wanting to assimilate us all.  

Well, for most of us, at least.  Once again, given the choice, I'd have to think about it.

My question, though, is what'd be next?  Daleks playing Laser Tag?  The Silence playing charades?  Weeping Angels playing hide-and-go-seek?  Seems like the possibilities are endless.

In any case, if it passes peer review, it's a pretty stupendous achievement, and it'll be interesting to see where the research leads.  We're probably still a long way from anything useful, but as I've learned from years of watching science news, sometimes those leaps can come when you least expect them -- and span chasms you thought would never be crossed.

Neil deGrasse Tyson has become deservedly famous for his efforts to bring the latest findings of astronomers and astrophysicists to laypeople.  Not only has he given hundreds of public talks on everything from the Big Bang to UFOs, a couple of years ago he launched (and hosted) an updated reboot of Carl Sagan's wildly successful 1980 series Cosmos.

He has also communicated his vision through his writing, and this week's Skeptophilia book-of-the-week is his 2019 Letters From an Astrophysicist.  A public figure like Tyson gets inundated with correspondence, and Tyson's drive to teach and inspire has impelled him to answer many of them personally (however arduous it may seem to those of us who struggle to keep up with a dozen emails!).  In Letters, he has selected 101 of his most intriguing pieces of correspondence, along with his answers to each -- in the process creating a book that is a testimony to his intelligence, his sense of humor, his passion as a scientist, and his commitment to inquiry.

A win for the good guys

I find it discouraging, sometimes, how often the hucksters win.  We still have homeopathic "remedies" on pharmacy shelves.  Selling supplements of dubious benefit and largely unknown side effects is still a multi-million dollar business.  Throw in all of the purveyors of woo who every year bilk thousands of people out of their hard-earned cash, and it all adds up to a pretty dismal picture.

But still, every once in a while, the good guys come out on top.

This  happened just this week with the announcement that the creators and marketers of the "Lumosity" brain-training games are being ordered to pay $2 million in reparations to customers who fell for their "unfounded claims that Lumosity games can help users perform better at work and in school, and reduce or delay cognitive impairment associated with age and other serious health conditions."

The selling points were attractive, with the aging population becoming increasingly (and justifiably) spooked by the specter of Alzheimer's and other age-related dementias.  I can understand the fear; I watched my aunt, my mother's older sister, outlive both of her siblings, finally dying at the age of 90 after spending the last ten years of her life essentially unresponsive and needing 24-hour care due to the ravages of Alzheimer's.  It's my worst nightmare, really.  The idea of having my body go on long after my mind is gone is absolutely terrifying.

So the claim that you could stave off dementia by playing some computer games was appealing.  So, too, were there other claims -- that you would improve your performance at work, at school, and on the sports field, feel more alert, perform cognitive tasks more quickly and accurately.  A direct quote from their advertisements said that playing their games three or four times a week would help users to reach "their full potential in every aspect of life."  With that kind of claim, it's understandable why people fell for their sales pitch.

The problem was, it had no basis in fact, and the Federal Trade Commission is requiring Lumos Labs, the company which created and marketed Lumosity, to refund money to their customers because they were participating in "misleading health advertising."

"Lumosity preyed on consumers’ fears about age-related cognitive decline, suggesting their games could stave off memory loss, dementia, and even Alzheimer’s disease," said Jessica Rich, Director of the Federal Trade Commission’s Bureau of Consumer Protection.  "But Lumosity simply did not have the science to back up its ads."

In fact, it wasn't simply a lack of evidence; there is significant evidence against their claims.  A 2014 joint statement from Stanford University and the Max Planck Institute said that "The strong consensus of this group is that the scientific literature does not support claims that the use of software-based 'brain games' alters neural functioning in ways that improve general cognitive performance in everyday life, or prevent cognitive slowing and brain disease."

But flying in the face of scientific evidence wasn't the only problem.  The FTC found that "...the defendants [failed] to disclose that some consumer testimonials featured on the website had been solicited through contests that promised significant prizes, including a free iPad, a lifetime Lumosity subscription, and a round-trip to San Francisco."

So promoting falsehoods for profit + paying people to give you good reviews = a $2 million penalty.  Which is exactly as it should be.

It's high time that the FTC crack down on these spurious claims.  You have to wonder how long it'll take before they can get the supplement-and-remedies cadre to stop hiding behind "This product is not intended to diagnose, treat, or cure any human illness" as a catch-all disclaimer and general Get Out of Jail Free card.

In any case, I find the whole thing heartening.  I do believe in the principle of caveat emptor, but we sure as hell wouldn't have to invoke it quite so often if the powers-that-be would pull back the reins on the false advertisers.
