If historic Broadway theaters in NYC transitioned to blocks of server farms, then many people would have a feeling, "Singing and dancing and live art used to happen here, and that history is worth continuing, here," even if for economic reasons it wouldn't and couldn't anymore. . . and so I don't think it's only wistful or wishfulness speaking.

It's positive to believe that places where creativity happened and was on display and at least nominally prized were places that need to continue in some form or fashion. I agree with you that the form and fashion may just be less visible now to these people wherever it has moved on to, now.
