[Néa, CdM] Seeing that post reminded me of a thought I had in Hong Kong, which is that it appears to be rapidly approaching a phenomenon closely related to the 'Shoe Event Horizon'. Currently perfectly good 20 storey buildings are being torn down to make space for 40 storey ones. This demolition increases the pressure on commercial space, thus increasing the value of the space in those buildings. Before long, before a building is complete the most advantageous thing to do economically will be to pull it down again and start buiding an even taller one. This process then becomes a self-reinforcing spiral.
