“In the travellers’ world, social media have enlarged the generation gap. The internet has brought a change in the very concept of travel as a process taking one away from the familiar into the unknown. Now the familiar is not left behind and the unknown has become familiar even before one leaves home. Unpredictability – to my generation the salt that gave travelling its savour – seems unnecessary if not downright irritating to many of the young. The sunset challenge – where to sleep? – has been banished by the ease of booking into a hostel or organised campsite with a street plan provided by the internet. Moreover, relatives and friends evidently expect regular reassurance about the traveller’s precise location and welfare – and vice versa, the traveller needing to know that all is well back home. Notoriously, dependence on instant communication with distant family and friends is known to stunt the development of self-reliance. Perhaps that is why, amongst younger travellers, one notices a new timidity.”
