Sometimes we just don’t learn until we make mistakes and actually experience the consequences.
We (all 67m of us and the wider world too) have quite a bit of learning to come from Brexit.
I hope as a result of that learning we will end up with a more socially cohesive, globally open, evidence-based thinking species. The questions are: how much pain we will have to work through in the meantime and how many years / decades it will take to learn the lessons and get better.
It’s still the best time in the history of the world to be alive. I think we and our kids will still be able to say that in 2040 and will look back on the referendum result as a painful mistake that taught us all a great deal rather than the point at which everything started to unravel irreversibly.
The young people of today will be in charge then.
