A Machine Smarter Than Me – Computers That Ignore

Posted by on Friday, 6 March, 2015
Robot's Revenge

MAYBE WE GET A REPRIEVE?

REPLACED BY MACHINES?

Sooner or later, robots will win. They will get all the jobs.

What will be do for money? Will we get weekly checks? From whom?

I wouldn’t worry. Our ever so smart political leaders are probably working out the details.

Aren’t they?

We’ll get to all that in another post.

– – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – –

Today’s article is about the possibility that robots, even the cute ones with big eyes, could muscle us out entirely. Take aways our jobs? Sure. But, even worse, they could take it all.

Robots one. Humans zero.

Stephen Hawking says we could screw the pooch because we didn’t think things through when we had the chance. He says robots could pass us right by in the brains department. Once they’re smarter than us, the ungrateful little clankers won’t mind chucking us into the excess baggage bin.

Silly?.

Bill Gates agrees with Hawking. Elon Musk agrees with both of them. Musk says artificial intelligence is “summoning the demon”. It’s potentially worse than nuclear weapons. Others who, supposedly, know what they’re talking about – experts in artificial intelligence and such – agree too.

Seriously?

MISTER Science AintSoBad thought he better look into this. So he read up on it – especially stuff by Nick Bostrom (Founding Director of the Future of Humanity Institute at Oxford Martin School). Bostrom, well respected and influential in neuroscience, technology, physics, and philosophy, has written a book. SuperIntelligence: Paths, Dangers, Strategies. Bostron’s book is serious and thoughtful.

Here’s the thing.

Bostron says we’re jaded.  There’s been so much crazy talk about computers taking over that we have tuned out.

I’m not sure.  He could be right. You don’t need proof that computers are getting smart, do you? Phones, robots, navigation systems, refrigerators, thermostats. It’s weird how they know what you’re thinking before you do.

They’re just contraptions. They don’t really think. That’s for sure.

For pretty sure, anyway.

Could they develop a “sense of self” and become conscious as these experts warn?

There’s room to worry because the way these things get programmed is changing. The traditional techniques have taken us a long way but AI (Artificial intelligence) researchers have caught on to the idea that you can’t program a machine to be be self aware. They’ve tried it and it hasn’t worked. If there’s any hope of truly cognitive machines, computers have to program themselves to get smarter.

That’s the corner that got turned.

That’s what scares the crap out of Hawking and Gates and Musk.

After figuring out that we don’t know what kind of instructions would get computers/robots over the consciousness hump, researchers are trying out new approaches – things that might  lead to consciousness. These systems include genetic algorithms, neural nets, support vector machines, decision trees, and naive Bays.

Bostron says we probably won’t know there’s been a breakthrough until it’s too late. Once computers get close to human intelligence, they aren’t likely to stay at that level very long. They will quickly pass us. The danger is that they might not turn out to be sentimental types. If they don’t see a benefit in serving the human race, they may change course and become a nuisance. Or even worse.

With computers and robots controlling so much of what we depend on, those mischievous little devils could be a very big problem. We need to figure out exactly what we need to include in those computers so that we are reasonably protected against an emerging consciousness. We need to understand our responsibilities as owners of sentient things, as well as how we can insure that those sentient things are happy to work in our (and their) mutual interest.

This is a major undertaking as it requires worldwide cooperation – something that we aren’t very good at.

MISTER ScienceAintSoBad suggests that we get on it.

Now.

NEW DOOHICKY FROM GOOGLE MAKES PASSWORDS A THING OF THE PAST.

Posted by on Thursday, 5 December, 2013
Funny cartoon about teens and passwords

GOD FORBID YOU WOULD SHOWER!

PASSWORDS

MISTER ScienceAintSoBad has many passwords. I keep a list. If it ever fell into the wrong hands, a stranger – maybe a scientologist or an astrologer  – could impersonate me. A fake MISTER ScienceAintSoBad could ruin  our relationship. I would hate that. So I work hard to protect my list of passwords.

You’re careful with your own passwords, right? But not everyone is as crazy meticulous as you. Most people do stuff like 123456 for their passwords. And use it over and over too.

Stupid? I guess. But people have other things on their minds. And they usually get away with it.

Sometimes they don’t.

Billions and billions of dollars are lost to account hacking. McCafee said it might be a trillion dollars worldwide. Maybe it’s not that bad. But it’s bad.

Supposedly, every single account should have its own login and password. And these should be changed often.

And crocodiles?

They have wings and a single horn in the middle of their snouts.

Most people aren’t ever going to manage their passwords right. They’re just not.  As long as we rely on people using passwords right, we’re pretty much screwed.

So Google has developed a device that can make passwords unnecessary. It has as much of a stake in getting rid of passwords as anyone.

Here’s its plan.

YubiKey Neo

Google wants people to own a thing.

Right now it’s called the Yubikey Neo. It will probably get a better name and a cute Google-like icon. The Yubikey Neo has  some impressive technology behind it and it’s already gaining support from other big players who don’t like passwords either.

Where did I find this?

It’s in an article by Amadou Diallo (Forbes Magazine) which describes the idea. Yubikey Neo plugs into the USB port of your computer. Or your tablet or your phone.  When it’s plugged in, security gets easy.  Once you log in, all you need is a simple four digit pin.  The real security is in Yubikey Neo.

The first version  is only for stuff with NFC (Near Field Communication chips) – mostly Android phones and tablets.  The “pilot project” has gone great. It shouldn’t be too too long til the wraps come off publicly and, by next year, it should be available for non-NFC stuff meaning pretty much everything.

MISTER ScienceAintSoBad likes this. PayPal, Mastercard, Lenovo, LG, and NXP are already lined up. That means it should have a good chance.

I hope so.

IBM’s Doctor In A Box

Posted by on Wednesday, 7 November, 2012

DR. KNOW-IT-ALL

What if your doctor knew everything?

Instead of just acting like he did.

I mean what if your physician ACTUALLY had all those studies and papers – all the latest stuff – in his.her head?

Nobody’s saying doctors aren’t smart but they can’t be up on every possible disease or every possible drug. Nobody could keep all that information “upstairs”.

Except for Dr. Watson.

The latest incarnation of  Watson, IBM’s supercomputer, takes in the Internet as well as other sources of up-to-date medical information, sorts out all the useful stuff, and  shares this with busy medical professionals as it is needed. Easy access to everything. And an algorithm to help.

Maybe you remember Watson. From Jeopardy. Watson was a contestant on the show and trounced  all the other (human) players.

They never had a chance.

IBM now wants to get Watson in the medical game, offering direct help as well as second opinions to physicians. Maybe, eventually, aiding and abetting the delivery of primary health care. (This, by the way, is from Brandon Kleim, Wired Magazine).

Would it work? Is this a good idea? Well… doctors do make mistakes.

No. I’m serious. It can happen.

Like.. all the time.

Thousands of errors every year. People who should get better, don’t. People who should go home, die. Not knocking the docs. They are amazing. But nobody’s perfect, right?

“I am. I am.” (Shut UP Watson!)

Okay. That’s the idea, anyway – that a machine, indefatigable, without human biases, with always up-to-date information – can offer useful assistance to healthcare providers.

So.

Nobody’s threatened by THAT idea, right?

One of the doctors quoted in the article above reminds us that doctors have enough knowledge. No need to waste electricity. We’re fine here.

Mister ScienceAintSoBad will stand aside while the geniuses from medical school figure this out. Some would say that most medical errors can’t be prevented this way. Well, guess what? This one’s inevitable. Watson, Shmatson. Eventually? The strong right arm of every physician will be his Doctor In A Box.

I’m right on this.

Trust me.

Love,

MISTER ScienceAintSoBad.
