Anki, the San Francisco startup behind AI-imbued robotics toys like Overdrive, Cozmo, and Vector, today shuttered its doors after raising close to $200 million in venture capital from Index Ventures, Two Sigma Ventures, J.P. Morgan, Andreessen Horowitz, and other investors. From a report: According to Recode , it'll lay off its entire workforce of just over 200 employees, each of whom will receive a week of severance. A failed round of financing was reportedly to blame. CEO Boris Softman told employees last week that a deal failed to materialize "at the last minute," as did acquisition interest from companies such as Microsoft, Amazon, and Comcast. Anki claimed to have sold 6.5 million devices total, and 1.5 million robots last August alone. (Cozmo was the top-selling toy on Amazon in 2017 with a community of more than 15,000 developers.) And in fall 2018, the company revealed that revenue was close to $100 million in 2017, a figure it expected to beat the subsequent year.

Gizmodo contributing editor Andrew Liszewski remembers April 14, 1999, "when at the COMDEX expo in Las Vegas, a now-defunct trade show similar to today's CES, Microsoft announced its IntelliMouse Explorer: a mouse that traded the dirt sucking rolling ball for LEDs and a digital camera that could optically track the mouse's movements with extreme precision." Based on technology developed by Hewlett-Packard, Microsoft's IntelliMouse Explorer arrived with a price tag that could be justified by even cash-strapped students like me. Even better, the underside of the mouse was completely sealed, preventing even the tiniest speck of dirt from penetrating its insides, and it improved on its predecessors by working on almost any surface that wasn't too reflective. I remember getting back to my dorm room and plugging in the Explorer for the first time, wondering who had a rig fancy enough to use the included PS2 to USB adapter. There were undoubtedly a few driver installation hiccups along the way, but once Windows 98 was happy, I fired up Photoshop and strapped in for the smoothest mouse experience I'd ever had. Problem solved.

In addition to that game-changing optical sensor, the IntelliMouse Explorer also introduced a couple of extra programmable buttons which seemed unnecessary to me at first, but it soon became an indispensable way to browse the web, letting me quickly jump forward and back between sites. (Tabs hadn't been invented yet.) It didn't take long for Microsoft's competitors to follow with optical mice of their own. Apple's arrived the year after in 2000, and in 2004, Logitech introduced a mouse powered by lasers. Extra buttons -- lots of them -- would eventually become the industry norm, and companies would soon find themselves competing with each other to see who could introduce the most accurate optical tracking technology to appeal to picky PC gamers.

I can count on my fingers the number of times a technology has thoroughly improved my life -- more often than not they tend to complicate things as well. (I'm looking at you, iPhone.) But 20 years later, the IntelliMouse Explorer is an upgrade that changed everything without any downside.
