|Possibly not the pub of the future|
For the other 99% of the population, convincing them of the value of face-to-face conversation as opposed to social media may be difficult. Go into any pub outside the "rammed" times of Friday and Saturday night, and you'll see pretty much every customer (and staff member) fiddling about with a device of some description. I'm writing this in my local, and it's what I see in front of me now. In fact, not being glued to a phone is probably grounds for service refusal these days, as you may be too drunk to focus on a screen.
In most situations, trying to separate people from their oh-so-essential social media is doomed to failure. Despite the predictable protestations to the contrary, people actually prefer dealing with others through the Internet than the risky and messy "traditional" methods. Not only can they edit what they say before saying it, but it gives much more opportunity for grandstanding narcissism which most people are, sadly, prone to.
As someone writing this on a tablet in a pub, I'm aware of the irony. But, unlike most, I have no problems admitting I'm a miserable, misanthropic bastard who prefers to deal with others at a distance. I assume most people don't think of themselves this way, despite the vast amount of opposing evidence.
So, despite the alleged success of Mr. Tyler's Faraday-caged bar, perhaps the modern licensee with an eye to continued trading would be best advised to work with social trends rather than against them. It may work for the odd place, but for most it'll be doomed to failure.
We've now reached the point Ian MacDonald predicted 20 years ago, a "multifocused and fragmented techno-decadence into which the First World is currently sinking as if into a babbling, twinkling, metronomically pulsing quicksand."
MacDonald indicated what he thought of this by committing suicide in 2003. But the rest of us have to accommodate it and move on.
