Earlier quoted context omitted.
Speaking as a boring professional, yes, artists may be insufferable in plenty of ways, but boring they are not and their presence is important for establishing and growing a local culture, whereas professionals are good for growing an economy and both are needed for a healthy, vibrant city.
I know some artists, and many of them are definitely boring :-) Just because someone decides to be an artist and sticks seashells on a model house doesn't make them interesting. And why would, for example, playing a trumpet well make you intrinsically more interesting than mastering complex mathematics? I'd rather have lunch with the mathematician. In fact, Feynman is at the top of the list of people I'd like to have…
It sounds like you know some pretty terrible artists, though. I mean, seashells on a model house?
PS. Feynman is Feynman for a reason.
