I couldnt think of a more huberis title if i tried 

 Serious question, when has any new tool “benefited all of humanity”? Where do these commies get these ideas? 

 Printing press 

 Good example!
Anything in the last hundred years though? 

 Transitors 

 Both of those (printing press, transistor radio) did bring in a new era of propaganda for most people though
