“…However, efforts remained fractured by lack of shared software and the cost of hardware development. Most of the attempts that were actually operationalized like the Connection Machine in 1985 (Taubes, 1995), Space in 1992 (Howe & Asanović, 1994), Ring Array Processor in 1989 (Morgan et al, 1992) and the Japanese 5th generation computer project (Morgan, 1983) were designed to favor logic programming such as PROLOG and LISP that were poorly suited to connectionist deep neural networks. Later iterations such as HipNet-1 (Kingsbury et al, 1998), and the Analog Neural Network Chip in 1991 (Sackinger et al, 1992) were promising but short lived because of the intolerable cost of iteration and the need for custom silicon.…”
