I don't know if you knew this or not, but at one time in the not too distant past, the internet as a whole was a curiosity only used by geeks. And before that, only total nerds in their mom's basement used personal computers.

Yes but from that it does not follow that filecoin will experience the same kind of growth.

  Internet = Once curiosity, small, for geeks

  Internet = Success

  Filecoin = Is curiosity, small, for geeks

It is untrue that automatically follows

  Filecoin = Success

It’s been used to prevent denial of service, such as in the Catalina succession vote.
