Yes, it is used in a professional capacity.
But when I say "niche hobby software," I'm talking about the relative scale of the user base.
Every working adult who touches a computer in 2026 is using office software. Photo editing is so common that "Photoshop" has become a verb. These two use cases are behemoths compared to 3D modelers.
It's either "niche hobby" or "embraced by professionals".
