Wtf? Sure, making a decent VM that can actually do something is no empty feat, but that just means that he's not only a designer but also a programmer. It's not like you're stamped "designer" on your forehead at birth and that's it, you know.
I have a friend who can code and bake excellent pie. Amazing!!
Being good at two things is more impressive than being good at one thing. Making a full featured VM is something that even lot of professionnal programmers can't do. The implication that you are "stamped" something at your birth was totally absent of GP's post.
Most designers can hardly FTP files to their server. Using the terminal is a terrifying idea. Writing code is a mountain of difficulty. I only know because I went through it myself.
