Are Fintech companies leaving the U.K.Watch
Many tech companies are either looking to move to the EU fully or at least setup a separate office.
Initially there will be a mass move (some have already).
Brexit should be seen though as a slow motion event over the next 15 years.
So, there will not be a massive event or financial issue.
There will be a set of smaller events over the next 15 years.
So, if you look at events day to day, nothing much will change.
After 15 years, if you compare people living in the EU (Germany & France) with the UK then the UK will look tired, worn out and poorer.
i.e. it is a 15 year event. An economic slowdown in slow motion over 15 years.
"But Google/ Facebook/ other company is opening new offices in X Y Z"
Yes. They are just offices. For larger companies/ banks etc. They are nothing, just offices.
As Google explained in a recent conference,
They currently see Europe are: London and EU/Berlin/others.
Now it will be: More mixed and eventually, mostly EU
AI (number of maths graduates) may stay in the UK, but it will move eventual.
