When you change the world and no one notices
It's also worth keeping in mind the Saganism    But the fact that some geniuses were laughed at does not 
    imply that all who are laughed at are geniuses. They 
    laughed at Columbus, they laughed at Fulton, they laughed 
    at the Wright brothers. But they also laughed at Bozo the 
    Clown.


We can see what is currently being laughed at.  Bitcoin stands out as a good example.   History will decide if they were geniuses or clowns.  All we have at the moment are opinions.On the other hand there is a particular form of sneering dismissiveness that I see from a few people that I use as a guide.  In the Bitcoin case all the right people were panning it so I grabbed a few for $11 each, that worked out well.
