I believe Brexit is a loose-loose deal. It's bad for the UK because it causes a lot of complications without producing real benefits. Basically, the UK will loose lot of political influence and control while having to abide to the EU's trade rules anyway. It's bad for the EU, because the union may loose cohesion, as it may turn out that the UK is doing not so bad after all and local anti-European socialist and nationalist movements will capitalize on that a bit, because the EU looses influence on the US without the UK, and because the UK provided a counter-balance to the axis France-Germany and now smaller countries fear that the EU will move forward faster than they wish for.

My prediction is that the net result will make everyone a little worse off in 10-20 years from now than if the UK had stayed in the EU, but the effect will not be very noticeable and overall hard to quantify.
