In London, there's a "Czar" for what is called the night time economy (I think it's such a ridiculous description, akin to other trendy but misleading descriptions like the "gig" economy).
The idea is to have, on Fridays and Saturdays, all the tubes running all night. How long before some bright spark suggests 7 days a week instead? At the moment, about four tube networks do this but I think more will be added. So presumably shops, cafes, clubs, casinos, bars, pubs, restaurants, etc., will also be more likely to remain open all night.
I'm not sure I want a Czar for this project. I don't think a 24-hour culture is a natural or a good thing. I realise that some people have to work nights because of the nature of their work, but I don't think it's something to aspire to for everyone - and will be particularly disruptive and unhealthy for people employed in those sectors.
