Brexit has an equivalence in quantum mechanics. Right now there is a super imposition of all states/possibilities. We can not know the position or outcome. No matter how radical the outcome it will become orthodoxy in time and you will know the true position you are in.

Psychologically
When this baby Brexit is born it will slowly develop. You will go through a phase where Britain will think Brexit is still a joke like peek a boo game because you have not learned object permanency yet. A true position will emerge whether there are any benefits as self awareness develops.

Some forecasts of disasters or legendary traffic jams in the Chunnel have only helped to make the crises to become more manageable.

As orthodoxy = radicalism + time you will learn your worst fears and best hopes will only be understood after a full year passes.

At this late date I see this baby is coming for good bad or indifferent. imo
