A thought I just had while pondering a small home automation system I am researching (is this legal )
I often hear the saying that "necessity is the mother of all inventions", but I wonder how many inventions ( either devices of systems ) were made by men ( or women ) who didn't have time on their hands to ponder the challenge and tinker until a solution was found ?
Logic from this tells me that in days gone by, it must have been the aristocratic / wealthy who had time on their hands and resources to do these things.
I see programs about inventions on dstv and often wonder just how the inventor kept down a day job and still had time to tinker - maybe most of them didn't have to work.
I suppose that now-a-days most inventions by the "working class" are done mainly while in the employ of a corporate that can fund the R&D.
