What's the UK got going for it?

I do a lot of doomscrolling. My YouTube feed is full of ragebait about how the UK is dying, we're in managed decline, the US has us trounced, etc. etc.

I want some glimmers of hope, please. What are some areas where the UK has untapped potential or we might see some chance of future prosperity? What're some fringe plans to get us to rejoin the First World? Lay some optimism on me, chaps!
