Here are four case studies on how machines can perform tasks that previously required human intelligence across various industries. The rise of artificial intelligence is the great story of our time. Leaving the laboratory after decades in the making, artificial intelligence, or AI, is infusing itself into many aspects our daily lives – from homes and phones to cars and offices. Machines are now able to perform tasks that previously required human intelligence across various industries. Insurance, once perceived as highly resistant to change, has now accelerated the race for innovation.

Facebook has announced the addition of new resources -- aided by artificial intelligence -- to help identify and support at-risk users, specifically those who may be suicidal. In a post on the Facebook newsroom blog, product manager Vanessa Callison-Burch, researcher Jennifer Guadagno and head of global safety Antigone Davis note, "There is one death by suicide in the world every 40 seconds, and suicide is the second leading cause of death for 15–29 year olds. Experts say that one of the best ways to prevent suicide is for those in distress to hear from people who care about them." Facebook already provides suicide prevention tools -- rolled out over 10 years ago -- such as offering tips on how to find support and the option for users to report posts that contain self-harm or suicide-related content. The company is testing a new tool to aid this process: artificial intelligence.

It has become an undeniable fact of life that people are going to Google their health symptoms. However, as most physicians are reminded every day by patients who come to the hospital or office armed with their smartphones or printouts of their search results, the internet often leads people to draw erroneous or even harmful conclusions about their health. Fed up with the confusion and misinformation of patients he was encountering as a third-year medical resident in 2014, Harvard Medical School student Andrew Le thought there had to be a better way. Over the past three years, Le and his colleague Eddie Reyes worked with a team at the Innovation Laboratory at Harvard to develop a digital health tool that would function as a health-specific search engine while also giving patients pointers and compassion along the way. "Right now, the status quo is Googling symptoms and getting scared. That is the front door of healthcare," Le told MobiHealthNews in an interview.

As the ancient Roman orator Cicero once put it, "The face is the index of the soul." In 2017, our faces are more index.html Nearly 250 million video surveillance cameras have been installed throughout the world, industry researcher IHS Insight estimated, and the global video surveillance market revenue is estimated to triple over a seven-year period, increasing to $42 billion in 2020 from $14 billion in 2013, according to industry predictions. Add to that surreptitious recording technology like drone cameras, Google Glass, Snapchat video glasses. Market researcher IBISWorld estimated the revenue for advertising agencies last year reached $44 billion, up 4% on the previous year. Face-reading technology can also now detect your emotions -- even those you don't realize you're projecting.

As technology is an industry that eats its young, it's rare to come across providers that have been around for more than a human generation. Among the household names today, IBM and SAS are the only ones spanning back over 40 years, with the difference that SAS has been continually growing and, after its early years, profitable. So the company, still under the leadership of founder Dr. Jim Goodnight, continues to forge its own path. Dr. Goodnight opened up last week's SAS analyst gathering with a demonstration using Alexa as the front end for SAS analytics. There's a bit of irony or coincidence here: SAS was founded just after the initial run of Star Trek, and 40 years later, the CEO gives a Star Trek-like demo of his products.

Flippy was developed by Miso Robotics and CaliBurger's owner, Cali Group. It uses cameras, sensors and deep learning software to locate ingredients in a kitchen without needing to reconfigure existing equipment. Not only does it position and flip the patties, it tracks their temperature and cooking time too. When the burgers are done, it alerts a human cook, who applies the cheese and other toppings. "Much like self-driving vehicles, our system continuously learns from its experiences to improve over time," said David Zito, CEO of Miso Robotics, in a statement.

Forget siloed quant teams, overworked developers or the superiority of the human mind, there's one big impediment to artificial intelligence really taking off in financial services – the current staff. If AI is to gain traction in financial services, it will need to vanquish the army of financial services professionals standing in its way. At least, this is the conclusion of Raffaele Savi, a managing director and head of developed markets within BlackRock's scientific active equities team. "People are problematic, machines are easy," he said, speaking at the Newsweek conference on artificial intelligence and big data last week. "People who understand finance and economics don't think the same way as people who know a lot about computing and machine learning. We need to work together as an industry. AI is where the bulk of alpha will be on a longer term horizon."

Last week, I compiled a list of the 5 jobs robots will take first. Today, let's have a go at the 5 jobs robots will take last. For this article only, let's define "robots" as technologies, such as machine learning algorithms running on purpose-built computer platforms, that have been trained to perform tasks that currently require humans to perform. For example, an assembly line worker performs mostly manual repetitive tasks which, depending on complexity and a cost/benefit analysis, can be automated. A CEO of a major multinational conglomerate performs mostly cognitive nonrepetitive tasks that are much harder to automate.

Diabetes can damage peripheral nervous tissue with the consequent loss of protective sensation. Increased risk factors include having diabetes for more than 10 years, being male, having poor glucose control, and having cardiovascular, renal or retinal complications. Patients should be advised to recognize early symptoms including loss of vibration sense, pain sensation, and temperature sensation in the feet. The American Diabetes Association recommends a multidisciplinary approach to management of foot ulcers and high-risk feet, particularly those with a history of ulcers or amputations. High risk patients should be referred to specialists for preventive care and life-long surveillance.

Artificial intelligence is everywhere and it's here to stay. Most aspects of our lives are now touched by artificial intelligence in one way or another, from deciding what books or flights to buy online to whether our job applications are successful, whether we receive a bank loan, and even what treatment we receive for cancer. We may have things better than ever – but we've also never faced such world-changing challenges. That's why Future Now asked 50 experts – scientists, technologists, business leaders and entrepreneurs – to name what they saw as the key challenges in their area. The range of different responses demonstrate the richness and complexity of the modern world. Inspired by these responses, over the next month we will be publishing a series of feature articles and videos that take an in-depth look at the biggest challenges we face today.
