Video games, computer systems, and a lot of consumer electronics were conceived of during the early childhood, teen years, and early adulthood of those people who are the same people who conceived of punk music.
I'm young, but from what I can hear from my dad, who plays bass, It was common to jam with friends, then play video games, watch cartoons, and maybe smoke a doob.
I bet a lot of chip musicians were into punk rock when it was in it's hay-day, and still are. So they make music that sounds like punk rock. And they talk about things that punk rockers talk about.
