The below saying has become a popular share around in social media:
“Big data is like teenage sex. Everybody talks about it, nobody really knows how to do it, everyone thinks everyone else is doing it, so everyone claims they are doing it.”
Indeed, there is quite a lot of hype around big data as for example told in The Big MDM Trend.
The teenage sex joke isn’t new at all. It has been used about a lot of new trends. I remember when the e-Business hype started, the joke was used here as well as you still can find some evidence about if googling the saying and getting this and that.
Today e-Business has matured and maybe a few brick and mortar bookstores have stopped laughing about the e-Business and teenage-sex joke now.
Also, maybe the joke says more about parents’ knowledge about teenage-sex.
