Well, with Movies and TV shows dealing with the possibility/existence of life on other planets like Roswell, X-Files, Star Trek, etc... I think once the news that aliens hit mainstream, people would be more curious than scared.
IMO, it would be too arrogant of man to think that we're the only ones around and besides, considering this possibility gives people something to do, it also generates jobs

Over-all, it has its role in the economy.
On the other hand, as far as the computing industry goes, if these beings are truly more advanced that us, imagine if we can over clock our old P4s to 10GHz without breaking a sweat, advanced memory multipliers that dynamically adjusts to the computing needs of the programs being run as well as dynamic storage media that just keeps growing and growing. Now that will be something, eh?
Anywho, nice story... We come in peace
