Artificial intelligence (AI) software has become such a staple of science fiction that most people think of it as a futuristic technology that may or may not ever become a reality.
But the truth is, most of us are already using AI software every day.
Every time you talk to your smartphone, conduct a Web search or check a social media feed, you're interacting with artificial intelligence. AI software plays games with us, composes music and writes movies. You're becoming more and more likely to encounter AI every time you do some online shopping as well. In fact, Gartner predicts, "By 2020, autonomous software agents outside of human control will participate in five percent of all economic transactions."
Somewhat more ominously, the same Gartner report forecasts, "By 2018, more than 3 million workers globally will be supervised by a 'robo-boss,'" and "By 2018, 45 percent of the fastest-growing companies will have fewer employees than instances of smart machines."
Those sorts of predictions have some people worried about losing their jobs. Others, including luminaries like Elon Musk and Stephen Hawking, have issued warnings about the potential for AI to become dangerous. They are part of group called the Future of Life Institute, which says that intelligent machines could pose an "existential risk" to human life and is supporting research efforts dedicated to making sure that AI remains beneficial.
So far, no AI software possesses anything near the capabilities that would be necessary to endanger human life. Instead, most AI software is dedicated to far more mundane tasks like understanding natural language, identifying objects and faces in pictures, offering shopping recommendations and finding answers to common questions. However, this technology is progressing at an extremely rapid pace. Many AI agents employ machine learning techniques to become "smarter" over time, and many technology companies both large and small are actively investing in AI research.
The list below includes 45 of the most interesting artificial intelligence projects currently underway. The first half of the list focuses on the efforts of some of the world's largest technology companies, while the second half details some of the work being done in the open source community and at smaller vendors. This list is by no means comprehensive, but it does include much of the most noteworthy AI software known to be under development.
Big Blue was one of the early pioneers of artificial intelligence, and introduced the masses to modern AI when its Watson system took part in the television game show Jeopardy. It generally refers to its AI solutions with the term "cognitive computing," and it sells them under the brand name "Watson." It has dozens of different AI products and services available, and they generally fall into two categories: developer tools and premade applications that use Watson technology. The company is also sponsoring a $5 million competition that challenges startups to use AI to "tackle some of the world's grand challenges."
1. Watson APIs
Designed for developers, these tools allow other companies to utilize Watson cognitive computing capabilities in their own apps. It currently offers about 19 different APIs with capabilities like concept expansion, conversation, language translation, personality insights, tone analyzer, relationship extraction, speech to text, text to speech, visual recognition and analytics. They can be accessed through the IBM Watson Developer Cloud service.
In the Watson Marketplace, IBM offers applications it has built that are based on its cognitive computing technology.

In March 2016, Microsoft set loose an AI chatterbot named Tay that was designed to interact and learn from people on Twitter. In less than a day, other Twitter users had taught Tay to make racist and offensive comments, and Microsoft took it offline. It re-released Tay a week later only to encounter similar problems. The company says it plans to put Tay back on Twitter "once it can make the bot safe."
The social network has invested heavily in artificial intelligence, primarily through an internal group it calls. Facebook AI Research (FAIR).
