My son's disappointment is the exact problem that Mattel believes it can fix with Aristotle, a $349 voice-activated speaker launching in May that functions like Google Home or Amazon Echo devices. But rather than rule the entire house, Aristotle is built to live in a child's room--and answer a child's questions. In this most intimate of spaces, Aristotle is designed to be far more specific than the generic voice assistants of today: a nanny, friend, and tutor, equally able to soothe a newborn and aid a tween with foreign-language homework. It's an AI to help raise your child. "We tried to solve the fundamental problem of most baby products, which is they don't grow with you," says Robb Fujioka, senior vice president and chief products officer at Mattel.

If you pick up your iPhone and ask Apple's personal assistant software the age of Mets third baseman David Wright, you get a direct answer: Wright, born in 1982, is 34 years old. You also get some ancillary information: A photo, his height, a nickname that no one uses. Ask Google's artificially intelligent question-answering system, same deal. But until Monday evening if you were to ask the same question of Alexa, the Amazon system that powers the company's Echo devices, you got a much different response. David Wright, according to Alexa/Echo, is 234 years old -- by far the oldest person on the Mets roster or in professional baseball or in the recorded history of the human race. Wright may be injured a lot, but that's only because he's older than the Constitution of the United States.

Now there's a discover tab to help you find new bots. Facebook Messenger wants to be your one-stop shop for... everything. Want to check on your flight or buy some Nikes? The social network hopes you'll never leave its chat app. Facebook on Tuesday unveiled new features for Messenger that aim to give people more ways to communicate with businesses but cut out the tedium -- like talking to customer service people.

Samsung's new Galaxy S8 phone is stunning. But its $100 price hike is hard to swallow. That's how much extra you'll shell out for the S8, which starts shipping Friday for about $750 -- $100 more than the iPhone 7 and last year's Galaxy S7 when it launched. A larger sibling, the S8 Plus, goes for about $850. True, the S8 phones come with several refinements that, totaled up, are indeed worth more than $100.

My husband and I have a running joke where we have our Amazon Echo "compete" with our iPhones to see who does a better (i.e., more human-like) job of interacting with us. While there's no clear winner, Siri seems to have the edge for casual conversation, but Alexa can sing. I've noticed something else, too. We don't usually thank Siri or Alexa the way we would a clerk at a supermarket or an employee at an information kiosk, even though they're providing us with identical services. They don't care if we thank them, because they don't have feelings.

It's the quiet-but-pressurised noise of Samsung executives holding their breath as they wait to see if the new Galaxy S8 is the success they so badly need it to be. After the Galaxy Note 7 had to be withdrawn last autumn because of safety issues, the S8 really must not fail. I've been using the S8 and its larger sibling, the S8 for a week. So, is it sigh of relief or hard, disappointed exhale for the execs? The look of the Galaxy S8 is a refinement of the Galaxy Note 7 and the Samsung Galaxy S7 edge.

One of the technology terms I have encountered most on my travels of the past couple of years has been artificial intelligence. AI has been around as a concept for a long time, but until recently it seemed always a little out of reach. Today AI is a reality. It is present in our smartphones in the shape of intelligent assistants like Siri, and powers chatbots that deliver real-time customer service. It is my belief that AI will grow to become a mainstream element of digital transformation sooner rather than later.

Beyond our quantum-computing conundrum, today's so-called A.I. systems are merely advanced machine learning software with extensive behavioral algorithms that adapt themselves to our likes and dislikes. While extremely useful, these machines aren't getting smarter in the existential sense, but they are improving their skills and usefulness based on a large dataset. These are some of the most popular examples of artificial intelligence that's being used today. Everyone is familiar with Apple's personal assistant, Siri. She helps us find information, gives us directions, add events to our calendars, helps us send messages and so on.

Last year's Galaxy S7 and S7 Edge were excellent phones, and so was the Galaxy Note 7... until it started bursting into flames. While some within Samsung were tasked with figuring out what happened and how to prevent it from happening again, others were trying to build a phone that would make people move on. The Note 7 won't disappear so easily from our collective memory, but I have to hand it to Samsung: The S8 siblings are impeccably built, thoughtfully designed devices. It's not hard to look at these smartphones as the first steps on a road to redemption, and after a week of testing, I can confidently say these are two of the best smartphones money can buy. I just wish its virtual assistant wasn't so half-baked. Text and photos don't do the S8 ($750) and S8 Plus ($850) justice. From their rounded edges to their precisely formed metal-and-glass bodies, they feel like smaller, sleeker versions of the Galaxy Note 7. That's a hell of a compliment, battery insanity notwithstanding -- the Note 7 was a beautiful device and I'm glad that DNA lives on. The S8 and S8 Plus's rounded Infinity displays -- which are 5.8 and 6.2 inches big, respectively -- only add to the phones' appeal. We'll dig into these curved screens more later, but people seemed to like them enough that it didn't make sense to have non-curved flagships anymore.
