What worries me is what will happen come the day of the "divorce"?
It reminds me of the Millennium Bug back in 1999. I was only 2 years old then, but I've since read about the global panic that come 1st January 2000 a lot of computers & computer-dependent equipment around the world will crash because software wasn't programmed to cope with the near millennial year! But I think people were made aware of this bug in good time and did something about reducing the impact.
However, with Brexit, what happens to things like passports, driving licences, exchange rates, EU currency, investments in EU companies? What about EU laws that bind the UK to the EU? Will they be rescinded come "Brexit Day"? Will the divorce happen gradually over weeks and months?
No one seems to know, and we're just not prepared for the switch over.
