For me what's inspiring about lisp machines is not any particular implementation detail, but the very idea that working with a computer can be this immersive, holistic experience where everything is accessible and workable through a single, but multidimensional human affordance; language. That the APIs and code within a computer system can be the ergonomic inward counterpart to rich accessible user interfaces, just as a man works with his hands and looks with his eyes, but easily turns inward to think and imagine. This is what I felt when I got that leaked Genera image going in a linux VM several years ago.

Its fair enough to say that lisp machines had this or that hardware limitation, or that they weren't really compatible with market needs, but to criticize 'lisp machine romantics' like this article does is to fail to understand what really motivates that romanticism. Maybe you have to be a romantic to really get it. Romanticism is abstract, its about chasing feelings and inspirations that you don't really understand yet. Its about unrealized promises more than its about the actual concrete thing that inspires them.

(I'm also an Amiga romantic, and I think what inspires me about that machine is equally abstract and equally points to a human attitude towards making and using software that seems sadly in decline today)
