Interesting discussion on the day the "inventor" of Moore's Law says it may have run its course.
http://www.bbc.co.uk/news/technology-32335003computing technology wasn't available.
I remember in 1994 the RN deleted a hitherto "essential" requirement from an aircraft spec because the technology simply wasn't available. (Processor speed, RAM). I cited Moore's Law and took the chance it would be available at ISD, 2001. It was, and it's still in service.
Even companies with seemingly limitless cheque books who yearned after a lesser capability, like the BBC (!), didn't fancy funding it. Nowadays everytime we watch the news that MoD work is evident, yet I wager we didn't get a penny out of it. Probably nobody left in MoD who realises what they actually own the rights to.
