Meet the man who wants total unemployment for all human beings in the world

Hugh Loebner is offering researchers $100,000 to develop a computer that thinks like a human. But is that really the best use of artificial intelligence?

Take a moment to salute the majesty of human conversation. When we talk to each other, whether it’s about last night’s TV or the wisdom of a military strike on Syria, we are doing something far harder than sending a rocket to the moon. We did the moonshot decades ago but we still can’t make a machine that will hold a decent conversation.
 
On 14 September, researchers will gathered in Derry, Northern Ireland, to demonstrate their latest efforts. If any of them has created a machine that successfully mimics a human, they will leave $100,000 richer.
 
The money is being put up by Hugh Loebner, a New York based philanthropist. His goal, he says, is total unemployment for all human beings throughout the world. He wants robots to do all the work. And the first step towards that is apparently to develop computers that seem human when you chat to them.
 
It’s not a new idea. Alan Turing is credited with the first explicit outline of what is now called the Turing test. A human judge sits down at a computer and has a typed conversation with an entity that responds to whatever the judge types. If that entity is a computer, but the judge thinks it’s a person, the conversational computer program passes the test.
 
At the Derry event, the programs won’t compete directly. Instead, the judges will enter a conversation at two terminals, one of which conveys the thoughts of a human being, the other one being controlled by a program. The judge will decide which seems more human; if it’s the computer, that program goes through to the next round, where the challenges get harder.
 
So far, no one has won the big prize but every year the most convincing program wins a smaller amount. The creator of the last program to be rumbled this year will walk away with 4,000 of Loebner’s dollars.
 
Many people in this research field think the competition is a waste of time. The founder of MIT’s artificial intelligence (AI) laboratory, Marvin Minsky, once offered to pay $100 to anyone who can convince Loebner to withdraw his prize fund. Minsky’s problem is that the Loebner Prize gives AI a bad name. The programs are not convincing for long – steer the conversation the right way and you can unseat them fairly easily (you can see last year’s conversations here). Yet AI is in fact becoming rather useful.
 
Computers may not be able to hold a conversation with human beings, but algorithms that adapt “intelligently” to circumstances are starting to hit the streets: Google’s self-driving cars run on AI. The way phone calls are routed through a network relies on other autonomous, flexible programs. Email spam filters, speech-recognition software, stock-market trades and even some medical diagnoses routinely employ machines that seem to think for themselves.
 
Where the Loebner Prize is most useful is probably in providing a check on our enthusiasm. Researchers have created AI programs designed to look at CCTV footage and decide whether a crime is about to be committed. A rapidly moving limb suggests an assault taking place. Spotting a gait associated with fast running can be interpreted as someone fleeing a crime scene.
 
Similar innovations have been tried on the London Underground – a program looks for “suspicious” patterns of movement which indicate that someone might be preparing a terrorist attack or be about to jump under a train. Once the program has decided there is a risk, it will alert the authorities.
 
Though AI programs remain as flawed as those attempting to hold a conversation, let’s hope we won’t be tempted to cede all our liberties to them.

Why Barack Obama was right to release Chelsea Manning

A Presidential act of mercy is good for Manning, but also for the US.

In early 2010, a young US military intelligence analyst on an army base near Baghdad slipped a Lady Gaga CD into a computer and sang along to the music. In fact, the soldier's apparently upbeat mood hid two facts. 

First, the soldier later known as Chelsea Manning was completely alienated from army culture, and the callous way she believed it treated civilians in Iraq. And second, she was quietly erasing the music on her CDs and replacing it with files holding explosive military data, which she would release to the world via Wikileaks. 

To some, Manning is a free speech hero. To others, she is a traitor. President Barack Obama’s decision to commute her 35-year sentence before leaving office has been blasted as “outrageous” by leading Republican Paul Ryan. Other Republican critics argue Obama is rewarding an act that endangered the lives of soldiers and intelligence operatives while giving ammunition to Russia. 

They have a point. Liberals banging the drum against Russia’s leak offensive during the US election cannot simultaneously argue leaks are inherently good. 

But even if you think Manning was deeply misguided in her use of Lady Gaga CDs, there are strong reasons why we should celebrate her release. 

1. She was not judged on the public interest

Manning was motivated by what she believed to be human rights abuses in Iraq, but her public interest defence has never been tested. 

The leaks were undoubtedly of public interest. As Manning said in the podcast she recorded with Amnesty International: “When we made mistakes, planning operations, innocent people died.” 

Thanks to Manning’s leak, we also know about the Vatican hiding sex abuse scandals in Ireland, plus the UK promising to protect US interests during the Chilcot Inquiry. 

In countries such as Germany, Canada and Denmark, whistle blowers in sensitive areas can use a public interest defence. In the US, however, such a defence does not exist – meaning it is impossible for Manning to legally argue her actions were in the public good. 

2. She was deemed worse than rapists and murderers

Her sentence was out of proportion to her crime. Compare her 35-year sentence to that received by William Millay, a young police officer, also in 2013. Caught in the act of trying to sell classified documents to someone he believed was a Russian intelligence officer, he was given 16 years

According to Amnesty International: “Manning’s sentence was much longer than other members of the military convicted of charges such as murder, rape and war crimes, as well as any others who were convicted of leaking classified materials to the public.”

3. Her time in jail was particularly miserable 

Manning’s conditions in jail do nothing to dispel the idea she has been treated extraordinarily harshly. When initially placed in solitary confinement, she needed permission to do anything in her cell, even walking around to exercise. 

When she requested treatment for her gender dysphoria, the military prison’s initial response was a blanket refusal – despite the fact many civilian prisons accept the idea that trans inmates are entitled to hormones. Manning has attempted suicide several times. She finally received permission to receive gender transition surgery in 2016 after a hunger strike

4. Julian Assange can stop acting like a martyr

Internationally, Manning’s continued incarceration was likely to do more harm than good. She has said she is sorry “for hurting the US”. Her worldwide following has turned her into an icon of US hypocrisy on free speech.

Then there's the fact Wikileaks said its founder Julian Assange would agree to be extradited to the US if Manning was released. Now that Manning is months away from freedom, his excuses for staying in the Equadorian London Embassy to avoid Swedish rape allegations are somewhat feebler.  

As for the President - under whose watch Manning was prosecuted - he may be leaving his office with his legacy in peril, but with one stroke of his pen, he has changed a life. Manning, now 29, could have expected to leave prison in her late 50s. Instead, she'll be free before her 30th birthday. And perhaps the Equadorian ambassador will finally get his room back.
