Earth orbiting around the Sun wasn't either.

See the problem is not if you are a professional or not, but if the tool is.

If I do the laundry and the washing machine takes 4 hours to complete a cycle I'm still washing my clothes, but I'm not doing it using a professional tool

There's no place where I implied people using less than optimal tools are not professionals, I'm talking exclusively about tools.
