If you are looking for an answer to the question What is Artificial Intelligence? and you only have a minute, then here's the definition the Association for the Advancement of Artificial Intelligence offers on its home page: "the scientific understanding of the mechanisms underlying thought and intelligent behavior and their embodiment in machines."
However, if you are fortunate enough to have more than a minute, then please get ready to embark upon an exciting journey exploring AI (but beware, it could last a lifetime) …
The Lenovo ThinkPad X1 Nano is just the kind of powerful, light, and long-lasting laptop you'll want to take with you on post-pandemic business trips--and it's handy even now just because it's so easy to take all over the house. It also performs right there in the ballpark with other 11th-gen Tiger Lake competitors, and at a hair under two pounds, it weighs less than almost all of them. Equipped with an IR camera for facial recognition, a presence-detecting radar, a 2K display with Dolby Vision HDR, and a premium keyboard, the X1 Nano covers the most bases for corporate users, and we haven't mentioned the superlative battery life yet. But with only two available ports (Thunderbolt 4, at least), you'll need to invest in a USB-C hub to connect legacy accessories. Lenovo offers nine versions of the ThinkPad X1 NanoRemove non-product link on its retail website.
With movie theaters largely off the table and new game systems on the way it's the perfect time to upgrade to your home theater. Whether you're looking for a $50 stocking stuffer, a big-ticket new TV or something in between there are plenty of ways to improve the room where you spend a lot of your time. Faster apps, bigger screens and more control are right at your fingertips, so let's take a look at some of the best devices available right now. If you're looking for the simplest upgrade for your TV, the Streaming Stick fits the bill. It's USB-powered so you may not even need to find a nearby outlet and it's small enough to fit in a pocket when you're taking a trip (or staying with relatives) so you can bring your own apps and queues along for the ride.
Heading back to school this year may be unlike any previous year, but whether you're at home or in a formal classroom, you'll need a way to relax. Here are some devices that can bring the theater experience to rooms of any size, while leaving a few bucks left over for you to spend elsewhere. TCL's 5-series 4K TVs will give you a high-res screen with support for HDR10 and Dolby Vision HDR at a price that comes in under $300. The built-in Roku OS adds support for nearly every streaming app your parents have logins for -- HBO Max is the only major one missing so you'll have to live with HBO Now or HBO Go -- and it's perfect for use with a PS4 or Xbox One with auto-game mode switching. Three HDMI inputs mean there's room for expansion as you add additional hardware and the remote is easy enough to use that even your roommate can figure it out.
Sony's new X800H is a major improvement over last year's G model, with interface tweaks and more powerful processing. Dolby Vision HDR and Dolby Atmos have been added to the mix, along with a redesigned remote control that finally looks like something that belongs with a Sony TV. With social distancing measures in place, my testing has been relocated from the TechHive lab to my home office, where the 65-inch X800H ($1,000) that Sony sent me for evaluation made for a tight squeeze. I'm guessing Sony sent this size because the 55-inch and smaller models don't have the fancy almond-shaped X-speakers that increase audio quality. I didn't hear the have-nots, so I can't comment on the difference, but the 65X800H's audio is definitely a step above the norm in this price range.
At the end of last year Hisense launched the $10,000 100-inch 4K "Laser TV" projector we saw at CES 2017, and this year it's continuing to push that home theater in a box. According to president Liu Hong Xin, it has more sizes in development (80 and 88-inch sizes will be in its booth), and already owns 60 percent of the market share for 85-inches and above.
