Matt Lyles knows how some people in Seattle feel about tech workers.
"When I came here, I was trying to start a better life for me," he said. "I didn't think I would be harming other people in doing so, but that's kind of what I feel sometimes."
Lyles is a software development engineer at Amazon. He helps Echo, the company's voice-activated speaker, figure out which songs to play when someone says, "Play sad songs from Soundgarden."
