Will commercial supersonic planes become a viable way to travel?

This week's Question: NASA announced last week that it was resurrecting a supersonic aircraft called the Quiet SST (“QueSST”)  . The space agency believes that the traditional sonic boom can be mitigated into a soft thump, or “heartbeat.” Supersonic planes could potentially reduce cross-country travel times to two hours or less, and make a trans-Atlantic trip in a matter of a few hours. The question is whether commercial jet makers and airlines will use the design concept.  

What do you think? Will commercial supersonic planes become a viable way to travel?
