It tries to read everything, but you can flush it with control. If you notice it stopped speaking, you usually use some review commands to look at the last few lines. If you're looking for something specific, you'd usually use something like grep, even in situations where a sighted person could just glance at the screen.

might sound a bit insensitive. But is there a video I can see of this? I cant even imagine how this would look in the hands of an expert.

Not exactly what you asked for but the "Designing for the Visually Impaired" episode of the Roguelike Radio podcast has a blind player play a roguelike. The intro has a bit of screenreading but the gameplay is starting at around 1:15.

While listening, you should put on headphones and concentrate very hard. It's quite fast and other sensory input might be disturbing so also close your eyes.

Saqib Shaikh, a blind developer at Microsoft, gave this short talk on using Visual Studio: https://www.youtube.com/watch?v=94swlF55tVc

I realize this isn't a console, but I think it is a good demonstration of an expert doing typical developer activities.

No, not to my knowledge. I could probably find a podcast or two, there are quite a few of those aimed at a blind audience, but that's about it.
