Why Do We Still Have Semaphore Signals?

Network Rail invited me to take a tour of signalling through the decades, starting with the Littlehampton Signal Box - still operating semaphore signals - through to Three Bridges whree we visit the ASC (Area Signalling Centre) and then the ultra modern ROC (Rail Operations Centre) as well.

The Littlehampton Signal Box is due to close in the new few years … but I also get to ask, why do we still have semaphores signals and where might the last signal box be?
