It looks like a shot from a conference, but reverse image search only leads me back to the official golang website. It’s obviously a regular example image, but I’m just wondering where and who this is.
I found it on the playground at https://play.golang.org/p/7d1gS7_tdc0 and modified the example code to output the image on my laptop. I was just expecting the gopher or something, but this was a real fun surprise.
