I just had a discussion with a friend, he said he didn't believe in a social platform where people can also sell things. I replied by saying that for many platforms I didn't believe they would get big, like Facebook (because there were many forums/platforms before Facebook) or Instagram. So this opened my eyes. Never judge but do your research
I was around for the time that the internet started. I had discussion with people how email is different from internet. Most people I know never thought they would need to sent an email. We have letters right?
