That said, setting up a new thing in Cambridge, offering £40k starting salary (with intention for it to go much higher) has shown: 1) exceptional talent on my doorstep, 2) plenty of people to choose from, 3) immediate impact.
The downsides are real though - industrial space, while cheaper, is hard to find and significantly out of the way. There's also a lower ambition level and a lot of red tape.
I really think compared to other places in Europe the UK is in a far better place to start to excel. Things like aria, works in progress, renphil and more have such a presecence and it feels like people are excited about reasearch, progress and hardware.
