To me, as an EU national, Brexit has moved from making me angry to just making me uncaring about what happens to the UK. My business has now diversified to take on more EU clients, so the drop in the GBP actually means I make more money and can charge less to some clients, making me more competitive. I have an escape plan ready for when the economy in the UK is not attractive anymore, and my (relatively) substantial taxes will come with me. Same goes for my partner. If anything, this has been a wakeup call to take on more consulting and remote work, instead of trusting the flourishing market in London to always have a job ready for me. I'm also not sure 100% why British business would hire me as a contractor if they could hire native British speakers (I charge market rates, my niche is in high demand). So I think the UK will have an issue with skills if/when educated EU nationals move shop. But that's just an educated guess.
