Photo being staged is not a good enough way to prove that the subject is not what he is claimed to be.
The guy might be hunched forward while actually working and might not be using as many devices, but still might be vibe coding.

I remember having a staged photoshoot where I was asked to sit with another person next to me on my work computer, acting like I we were discussing something on screen. I ran some fancy stuff on screen for effect.
While actually working, I used to mostly talk directly while we both were sitting on our own systems, but that doesn't change the fact that I worked there and had made said fancy stuff before.
