I think it's important to understand that Dreyfus doesn't think that AI is not possible, but that it's not possible via computation, i.e. computers. He considers consciousness and understanding as emergent properties, not something you can code. He also used Heidegger's concept of Dasein, "being in the world" as Dreyfus translated it, and argued that such being can't be programmed.
