"It is a mystery why the technology is taking so long to catch on in the accommodation sector when it is taken for granted elsewhere. It certainly seems popular with those guests that are offered it.

[..] if tech firms could only move more quickly on driverless taxis, takeaway food delivered by drones and automated bartenders, we could eliminate the need for social interaction entirely when travelling. Which, of course, would be grotesque. Perhaps Gulliver should be careful what he wishes for."
