Foundation was near-unadaptable as-is, given that it spans eras and wants the user to emotionally attach to the structure, rather than the individuals. For TV shows, audiences generally attach to characters (and the actors and actresses that play them), and the kind of story that allows a single cast to span eras would need to engage with some degree of time travel, cycles of life and/or abuse, or immortality, none of which fit in with Foundation.

That said, Neuromancer is a book that's more "cool" than good; Gibson is very good at painting pictures with words, but story itself is something of a convoluted mess. Hopefully an adaptation can give the writers a chance to smooth out the elements that don't work.
