Eli5: Why hasn't commercial supersonic flight been attempted on a wide-scale since concorde?

Surely in 14 years since the last commercial Concorde flight the technology would have advanced to the point we could think about this again?

The main issue is it just isn't worth it.

It cost about as much to fly the Concorde across the Atlantic as it does 747, which has three times as many seats.  

Not many people are willing to pay that kind of money.  3.5 vs. 7 hours might sound good, but super sonic speed doesn't get you through the security line any faster.  Door to door is more like 7 hours vs. 10.5, and that point you are blowing a whole day no matter what.
