I can't speak for gambiting, but I'm also going to leave the UK as a direct consequence of Brexit. It's not that it would be impossible to get some visa if I really wanted, it's that revoking the freedom of movement sends a strong signal that they don't want us here.
When I was choosing where I'd go for university, the UK wouldn't have even made the shortlist if moving here was even slightly more inconvenient than just walking in. The only thing the UK had going for it is that I already knew the language. There are plenty of other places in Europe where skilled labour is in demand.
