I also have a high level of privilege because my upbringing allowed me to have unmetered access to a computer at 14 landing me a good programming job when I dropped out of college. So from the perspective of someone who didn't even have the opportunities I had, looking into the life of someone who started a company from a shed while living in their parent's house, it would appear "Ultra" Privileged. (I have plenty of friends from where I grew up that didn't even have support from their parents when they were 14-16, working after school to pay rent because their parents either died, or were too deadbeat to consistently make rent)
Like I said, it's all relative.
Ultra means extremely. You were saying that simonswords82 was extremely privileged. In the US, (edit: Europe) having parents and a garage is somewhat common, though, I think.
Alternatively you could say that you were unprivileged, and he privileged (without ultra).
Oh well what does it matter
