The week in tech: tunnels, coolers, and bears. Oh my.

The tech world is looking ahead to next week's Google I/O conference, but there was plenty going in the technology realm this week. Here's some of the stuff you might have missed. Amazon proudly announced that its Alexa-enabled family of products grew by one member with the unveiling of the Echo Show, which has a screen for doing things like making video calls. Facebook's AI research group said they had created a faster, better language translation system using a neural network. Microsoft held its annual Build developer's' conference, where it talked about, among other things, forthcoming updates to Windows 10 and how it's going to use AI to make workplaces safer (watch that jackhammer there!).
