AI applications have been deployed and used for industrial, government, and consumer purposes for many years. The experiences have been documented in IAAI conference proceedings since 1989. Over the years, the breadth of applications has expanded many times over and AI systems have become more commonplace. Indeed, AI has recently become a focal point in the industrial and consumer consciousness. This article focuses on changes in the world of computing over the last three decades that made building AI applications more feasible. We then examine lessons learned during this time and distill these lessons into succinct advice for future application builders.

Slime mold, ants, and Amazon's product recommendation system may be making decisions the exact same way, according to a new study. To come to this conclusion, Bernd Meyer and his team studied the behavior of slime mold--which is not a plant, fungus, or animal, but a loosely organized network of individual cells--and stuck it in a maze. Both pathways led to oat flakes, which is apparently slime mold's favorite snack, but one of the paths was dark and the other was filled with a bright blinking light, which mold hates. The slime mold did the most sensible thing it could: have its cake and eat it, too. Or rather, have its oat flakes and recoil from the light. Paradoxically, the slime mold seemed to perform its tasks better with the interference.

The Samsung Galaxy S8 was announced Wednesday and brings to the market a host of new features to the Galaxy S line. From iris scanning and facial recognition to the Bixby AI assistant, the Galaxy S8 packs a host of functions in a frame than it smaller than Samsung's previous flagship models.

While the screens are much larger than prior Galaxy S devices, their overall size is similar to the Galaxy S7 Edge and the Galaxy Note 7.

When the Samsung Galaxy S8 smartphone finally goes on sale in April, the new flagship smartphone will also be available at a place that might initially seem surprising: the Microsoft Store. Microsoft will begin selling a Microsoft Edition of the Galaxy S8 and S8 Plus through its local Microsoft Stores. As with the primary Galaxy smartphones, it will also be available April 21. Externally and mostly internally, the Microsoft Edition of the Galaxy S8 features the same specifications and features as the main Samsung version of the smartphone. However, the Microsoft Edition of the phone will also automatically install a suite of Microsoft mobile apps during the initial setup process.

And there are some awesome features packed in.

Samsung has been bundling Microsoft apps like Skype, OneDrive, OneNote and more on its phones and tablets for a while now. However, when it comes to the Galaxy S8, the two companies are taking their partnership a step further. Microsoft is selling a Samsung Galaxy S8 Microsoft Edition and it's accepting pre-orders starting today at its retail stores in the US ahead of the April 21st launch. As you might expect, the customized S8 will come loaded with Microsoft's apps and services like Office, OneDrive, Outlook and Cortana. It's interesting that Microsoft's virtual assistant would be included given that these two new handsets are the big debut of Samsung's Bixby.

Could artificial intelligence make devices easier to use? According to Samsung, it sure can, and that's what it the company out to prove with its Bixby AI service. Bixby is being loaded on the Galaxy S8 and S8 smartphones, which were announced on Tuesday. Bixby is an agent that can help the smartphones talk, recommend, and remind, said Mok Oh, vice president of service strategy at Samsung. The AI service is being positioned as a more intuitive way to use and interact with smartphones.

People looking for an easier path to integrating with Amazon's Alexa virtual assistant have good news on the horizon. NoHold, a company that builds services for making bots, unveiled a project that seeks to turn a document into an Alexa skill. It's designed for situations like Airbnb hosts who want to give guests a virtual assistant that can answer questions about the home they're renting, or companies that want a talking employee handbook. Bot-builders upload a document to NoHold's Sicura QuickStart service, which then parses the text and turns it into a virtual conversation partner that can answer questions based on the file's contents. Right now, building Alexa skills is a fairly manual process that requires programming prowess and time to figure out Amazon's software development tools for its virtual assistant. People who want to change the way that a bot behaves have to go in and tweak code parameters.

Opinions expressed by Forbes Contributors are their own. The author is a Forbes contributor. The opinions expressed are those of the writer. The Samsung Galaxy S8 has landed and it's quickly winning over the tech press. But as the dust settles and the reviewers start, well, reviewing.

Alexa is making its move. While Amazon's virtual assistant has been tied to its own devices since its introduction more than two years ago, it is now beginning its an all-out assault on Siri and Google Assistant as it looks to establish a foothold on iOS and Android. But entering enemy territory isn't going to be easy. Apple and Google have both built their AI aides deeply into their mobile operating systems, so Alexa has to live inside apps for now. On the iPhone it's inside the Amazon shopping app, and on the Mate 9 (the only Android phone that supports it), it's accessible via a dedicated Huawei Alexa app. So to use it, you'll need to open the respective app before you can start asking questions.
