Actually, the sentence is quite alright. Lets break it up for you: 1)"Rarely has a technological development had as great an impact on…"= If you rewrite this as " It is rare for a technogical development to have such a great impact on…", we can go on to the next bit… 2)" as much aspects of…"= rewrite this as "many areas of" 3)"social, economic, and cultural development"= self explanatory. Last bit… 4)"as the growth of electronics"= also self explanatory. Combine them all, and you get " It is rare for a technological development to have such a great impact on so many areas of social, blah blah as the growth of electronics." Or to simplify the sentence:" Electronics has impacted so many areas such as social, economic, and cultural development, which is rarely the case in technology". I think the tougher question is why the author chose to write such a convoluted sentence for something so simple…

The sentence should have "many" instead of "much", and electronics is misspelled. A technological development has rarely had as great an impact ( on as many aspects of social, economic, and cultural development) as the growth of electronics. Hope that grouping helps.

The sentence is wrong?as much should be so many? A technological development has rarely had as great an impact on so many aspects of ... as the growth of electronics.
