It's a good time for autonomous tech

I never win raffles, but I finally did last week at the MIT Xconomy in Boston. My prize was a Roomba. These robotic vacuums have been around for years for personal use, but now hotels are using similar devices to not only automate the cleaning process but also most of the hotel functionality like check-in, check-out, food delivery, and the automatic folding of clothes. There's even a completely robot-powered automated hotel in Japan. As a service, automation is invaluable when done well.
