I think there is always going to be difficulty around making policy for the long term. That's the challenge you all face, being politicians.
Really, the key has often been seen to be to build flexibility into the facilities we're building so that they can change over time. The one thing we know is that there is going to be change over time. There are going to be emerging needs, there are going to be new technologies, and there are going to be new approaches to delivering—maybe even new approaches to maintaining—facilities. If we lock ourselves in over the long term, we might eliminate the possibility of the public's benefiting from those emerging technologies or those emerging uses for the facilities in the way they can be used and the ways they can be managed, and possibly miss out on the potential to lower the costs and deliver value for your constituents.
