Memory isn’t a big problem anymore. You have to be able only to copy and paste a link, not remember an entire epic poem.

And he had to tell all of his likeminded friends about it.

Evolution is how contagious ideas are created in the wild. Where there are lots of different ideas, and there is competition for mind space, only the most effective ideas will win.
