Future noir it's just cyberpunk since its conception.
Blade Runner it's film noir in the future, and Neuromancer it's a hardboiled mistery book with computers.
It has sense, a lot of pulp writers wrote both mystery and sci-fi booklets under diferent aliases, and a lot of plots were recycled by changing the setting.
