NEW YORK--Only a few years ago, the launch of a new computer operating system set off impassioned clashes between devotees of the Mac and supporters of Windows. Tuesday's arrival of macOS Sierra seems like an after-thought by comparison, coming with nowhere near the media attention that's paid to an iPhone or even iOS release. The marquee feature is Siri's debut on the Mac, and while this is mainly a welcome if long overdue development, the fact is we all got to know Apple's loquacious personal assistant on the phone first. Indeed, with Sierra comes further evidence that we're fully entrenched in a post-PC world, where the computers in our pockets have trumped those on our desks. Microsoft with Windows 10 has for the most part designed a single operating system that is meant to work across PCs, phones, tablets, even Xboxes.

The online dating service on Tuesday announced a partnership with music streaming site Spotify that will enable a brand new feature for those looking for a romantic match. Taking Tinder's swiping feature a step further, the Anthem will refer users who share similar musical interests. Tinder would pull "liked" brands and musical artists from Facebook pages, akin to the site's "common" or "shared interests" recommendations. In addition, Tinder is launching Tinder Music, which gives users set music themes that help them create their favorite playlists.

We're experiencing artificial intelligence every day of our lives, even if we don't know it or just take it for granted. Whether it's Spotify using machine learning to give us a better music playlist, or Apple using natural language processing to make Siri our digital assistant, AI is truly everywhere. As the leader of Salesforce's Marketing and Analytics Clouds, I want to outline what exactly intelligence means for marketing and analytics professionals. Starting from the top, we all know and can understand that customers expect faster, smarter, more personalized engagement. But delivering on these expectations is challenging.

Me: Siri, how are you tonight? Siri: I'm happy to be alive! Siri: OK, one option I see is Totto Ramen which averages 4 stars and is moderately priced. Looks like I'm going to be needing a Lyft. Siri: Lyft can be there in 6 minutes.

If you skipped the beta releases, today's the day you can put Siri to work on a Mac. Apple's latest desktop operating system, macOS Sierra, is now available for download. While the new version debuted back at WWDC and followed with a public beta, this is the first time the finished product will be available to the masses via the App Store on a Mac. In addition to the aforementioned virtual assistant hitting the desktop, the free update includes features like a universal clipboard, revamped Messages, a storage optimization tool, Apple Pay on the web and more tabs... lots of tabs. For a full rundown of the new features and our detailed impressions, consult out full review right here.

This is almost like part two of my macOS Sierra review. I had a chance to test Apple's newest desktop operating system at the beginning of the summer, just before it was released in a public beta. The software hasn't changed much since, but a few of the headline features were missing from that earlier build; Apple said they wouldn't be available until the final version shipped in the fall. As it happens, Sierra arrives today as a free upgrade, so I'm picking up right where I left off. What follows is my full review of Sierra, though if you read my earlier preview, or have been using the software yourself, you won't find many big surprises here.

Artificial intelligence (AI) is no longer a futuristic concept, it's a staple of today. From virtual personal assistants like Siri and Cortana, to image scanners built to identify diseases, to Google's or Tesla's self-driving cars, AI is becoming a part of everyday technology. According to a MarketsandMarkets report, the artificial intelligence industry is estimated to reach USD 5.05bn by 2020, growing at an annual growth rate (CAGR) of 53.65% between 2015 and 2020. One reason for this significant growth is the increased use of machine learning technology – a subcategory of AI where computers learn from data themselves in the advertising and media industry. Machine Learning has a huge impact on the advertising ecosystem already.

In April several news sources reported that the law firm of Baker Hostetler had hired a legal robot called ROSS. This artificial intelligence system, built on IBM's famous Watson system, automates legal tasks like research and the preparation of legal memorandums in the narrow domain of bankruptcy law. Since then, other big law firms have joined the rush. ROSS Intelligence markets its product as a kind of artificial intelligent assistant: ask it questions in plain language, and legal research is presented. It sounds a lot like Siri, except instead of asking for baseball scores one can ask for relevant case law.

Artificial Intelligence is the latest hotness. We've heard how bots are going to be the new apps allowing natural conversational interfaces. Siri, Cortana and Google Now are no longer a gimmick and are becoming more useful every day. Machine Learning sits behind artificial intelligence and on the surface it may seem like a deeply technical, scientific topic. We are here to tell you that it is more accessible than you think.

About eight years ago, I remember talking with Fortune 1000 clients about Cognos. You know, the tech that takes data, creates 1 version of the truth for you, and sends you pretty reports via email for you and your team to make optimal business decisions? Have you heard about Celia (AKA the Cognitive Environments Laboratory Intelligent Assistant)? Celia is Cognos on steroids -- well, she is Watson with human elements. You can ask Celia: What businesses should we, as a company, buy or sell?
