The actual name of the program (originally funded by DARPA) was 100 Year Starship Study (100YSS). It is a study of what would be necessary to actually have such a ship. There are LOTS of issues, time and distance being big ones, along with propulsion and power, and a whole lotta cultural ones.
I do wonder about the speakers and some of the format of this symposium. They are charging significant extra fees to see Nichelle Nichols and others talk at the various dinner events. That comes off more as fundraising than science symposium.
I will be attending the symposium, as a representative of a group that made a proposal to DARPA (SpaceGAMBIT) , but will not be at the extra cost events.
