You have said a lot of things that are correct but none more than this. I shouldn't have let my concerns about meeting future standards override my feelings about the present when the future is yet to come. Thank you for knocking some sense back into me. I appreciate it more than I can make clear.TL;DR: don’t worry so much.It’s impossible to know what the standard will be in the future, so even if these buildings need to be replaced at some point, there’s no good reason to get rid of them now.
