This is the real "computer use". We will always need GUI-level interaction for proprietary apps and websites that aren't made available in machine-readable form, but everything else you do with a computer should just be mapped to simple CLI commands that are comparatively trivial for a text-based AI.

I think websites via DOM are gonna be quite easy for the models.
