The arrival of March means we can finallylook forward to fledgling signs of spring, as well as South by Southwest Interactive—the technology-focused event that’s inspired a yearly cultural pilgrimage for early adopters and technophiles. PopMech will be on the ground at Austin, Texas, from Friday onwards to report on the chaos and bright new ideas that we see at the startup-swamped festival. This year, the VIP lineup includes science celebrities Neil deGrasse Tyson, Bill Nye and Adam Savage, along with some more surprising personalities, such as Edward Snowden and Julian Assange. (We hear Internet sensation Grumpy Cat will be in attendance, too.) Here’s a look at some of the trends and themes we think will emerge at the show.
