I’ve often heard the saying how “everything easy has already been invented” and that it’s so much harder today to invent new things.
I think it’s a fallacy. Things were just as hard in the past.
I owned an ISP in 1998 and there were plenty of search engines at the time. Google invented something unique and innovative and they were rewarded tremendously for it. There were literally hundreds of other companies trying to do the same thing but Google was better. If it was low hanging fruit then Hotbot or any of the other major players could’ve done it.
