Yep. Building a high-energy physics or an astrophysics experiment takes time (and money of course). On top of that, we have never any guarantee to get a result. Therefore, as soon as we have one, the entire community is happy ^^
PS: I have never met Brian Greene, but I have read a lot of good stuff from and about him.
Yes, Brian is fighting the good fight for string, most everyone else jumped ship, he related to the G-wave hunters saying lots of patience needed for either pursuits! (I guess Capitalized MONSTER replaced the lower case fractal iteration monsters)!
